Introduction
The Centre for Aerospace Systems Design & Engineering (CASDE) was setup within the
Department of Aerospace Engineering at IIT Bombay in the year 1998. The Centre was fully
funded by ARDB and was aimed at creating a centre for excellence in Systems Design &
Engineering. It should be noted that CASDE came into existence at a time when Design as a
discipline was at its lowest ebb. Design content in curriculum of most aerospace educational
institutions had substantially reduced by 1990s. No educational institution had faculty
engaged in research in design methodologies. IIT Bombay knew that the task of setting up a
centre like CASDE was complex. But substantial hand holding by DRDO laboratories and
careful nurturing by all has turned this experiment into a notable success. During the past 5
years, CASDE has been involved in the following areas and has made significant
contributions in most of them.
1. Initiating academic programme in Aerospace Systems Design & Engineering.
2. Initiating research in the area of design methodologies, especially MDO.
3. Setting up multi-faceted Integrated Modeling & Simulation Laboratory (IMSL).
4. Conducting workshops and professional development courses in specialized topics of
interest to Design Methodologies.
5. Setting up of a Special Interest Group (SIG) for aerospace designers and offering
national and international platforms to meet and exchange of ideas.
6. Promoting design among educational institutions through a variety of measures.
7. Facility development for MAV related activities and specific MAV studies.
8. Design and development of an autonomous MAV
The initial ARDB funding of Rs 180 Lakhs (excluding Rs. 12 Lakhs as IITB overheads) was
for a period of 3 years. But the funds have lasted for more than 5 years. However, the total
sanctioned funds would be fully utilized by March 2004.
Since June 2002 CASDE is working on the evolution of a viable model for its sustenance on
a long-term basis. The 3rd and 4th Meetings of Joint Policy Committee (JPC), CASDE have
deliberated on this issue and have provided important inputs in this direction.
The present write up reflects the viewpoints of core faculty of CASDE, as well as the
sentiments expressed by the JPC members, on (1) issues pertinent to the long-term sustenance
of CASDE and (2) a viable model for CASDE in Phase-II.
2
Operational Features of CASDE
CASDE functioning over the last 5 years has been organized into three key elements, as
described below.
1. First and foremost, it is a distinct entity called a Centre within the IIT Bombay Academic
and Administrative Framework, whose components and tasks are as follows.
An up-to-date, centralized, shared infrastructure in the form of office equipment,
communications facilities, library facilities, trained manpower etc.
Ability to coordinate visitors for increased interaction.
Support to (1) creation of short-term courses and their deliveries; (2) brainstorming
sessions, (3) workshops and conferences, etc.
These aspects together form the “Centre Element” of CASDE. It is this Centre
Element, which has acted as a common platform and a binding agent to bring together
CASDE core faculty. This has also enabled a framework to coordinate interactions with
other associated faculty from the departments of Aerospace, Mechanical, Electrical,
Computer Science from within IITB and wide ranging institutions outside of IITB.
CASDE has derived great strength from the Centre Element and the 4th meeting of JPC
of CASDE has also appreciated this aspect.
CASDE is of the view that the Centre Element is essential to (1) its long-term
sustenance and (2) its efforts to achieve global recognition in the area of Systems Design
& Engineering (SDE). In its absence, the binding force will be missing and, over a period
of time, the core faculty would get drawn in different directions, gradually losing the
present focus. JPC members in the 4th meeting of JPC of CASDE have also expressed
these fears.
The yearly cost of the Centre Element, during the last 5 years, has been around Rs. 15
Lakhs per annum and caters to the following expenditure heads.
o Office Equipment Procurement, Maintenance and Upgradation
o Books Journals, Magazines, CDs
o Trained Support Manpower
o Logistic Support to Visitors & Core/Associate Faculty of CASDE
o Support for CEP module creation, Brainstorming Sessions, Workshops
The Centre Element is presently funded by AR&DB and hence CASDE has oriented
itself heavily towards the various DRDO laboratories. It is CASDE’s view that, unless
funds for Centre Element continue to be provided by ARDB, focus may shift away from
DRDO. Therefore CASDE seeks funds from ARDB for Centre Element, at the rate of
Rs. 15 Lakhs per annum, on a continuing basis. It is felt that this would amount to a
recurring grant to CASDE from ARDB, without any time limit.
3
2. Second key component of CASDE functioning are the various Project Elements, which
are the various CASDE activities that were carefully configured through a well-conceived
process. All activities are within the overall objectives of CASDE as spelt out in the
proposal dated 1998 (http://www.casde.iitb.ac.in/History/CASDEOrigin/octcont.html).
The process of starting a Project Element is as follows.
o Project mode activities are initially discussed threadbare between core and
associated faculty of CASDE and also with Management Committee (MC).
o If substantial resources are required to be committed for the activity, a
brainstorming session is organized with participation of major DRDO
laboratories, ARDB representatives and SPC/JPC members.
o The activity is then reported to JPC/SPC meetings and after their approval an
internal allocation is made for the activity.
Some of the activities under Project Elements are as given below
I. Project Elements on Design Optimization & MDO
o MDO of flexible aircraft wing (WingOpt)
o 3-D Duct design using CFD and RSM/DOE approach
o Wing aerodynamic design using Multi-point RSM
o Airborne Early Warning System Optimization
o Maneuver Load Control for combat aircraft
o Conceptual design optimization of transport aircraft wing
o Comparative study of various MDO architectures
o Studies in gradient evaluation methods
o Formal Industry Standard MDO Framework Development
II. Project Elements on Modelling &Simulation and MAV Development
o Setting up of Integrated Modelling and Simulation Laboratory
o Development of Instrumented Flying Platform
o Design and development of Videography Platform
o Design and development of miniature solar powered aircraft
o Hardware-in-Loop Simulator for MAV Development
o Preliminary studies towards development of autonomous MAV
CASDE feels that all the activities mentioned above are of interest to DRDO laboratories,
as is evident from the organizational participation in Phase-I. CASDE has directly spent a
total of Rs. 80 Lakhs over a period of 5 years towards Project Elements. It is believed
that similar activities will continue to be of interest to the various DRDO laboratories.
There is, however, a scope for partial funding of some of the activities by DRDO/user
agencies and CASDE is willing to explore this possibility. It should be noted that CASDE
has attracted a Rs. 33 Lakhs Realtime Launch Vehicle Simulation Facility from ISRO and
an additional Rs. 21 Lakhs from IITB towards laboratory development
However, there is a component in Project Elements, which is generic in nature,
pertaining to fundamental R&D for methodologies. This is best funded by ARDB,
through a seed grant, on a recurring basis. Thus, CASDE requests ARDB to provide Rs. 5
Lakhs per annum for the generic component of Project Elements, without any time limit.
4
3. Last, but not the least, is the third key component of Awareness Creation Element,
which consists of Short term Courses, Workshops and Discussion Meetings that CASDE
has been organizing on a regular basis, through its internal resources.
Some of the important meetings organized by CASDE are listed below.
o 1-Day Workshop on Systems Engineering Education
o 2-Day Discussion Meeting-Cum-Workshop on Modeling & Simulation
o 3-Day CEP on Case Studies on Modeling & Simulation of Aerospace
Systems
o First Meeting-cum-workshop of SIG-MDO
o Short Professional Course on MDO in Aerospace Systems
o A Short Course on "Miniature Aircraft - Design, Build and Fly"
o One Day Workshop on MAV at IITB
o Workshop on Optimization Based Design & MDO
o A special session on “Engineering Systems”, as a part of the International
Conference and Instructional Workshop on Industrial Mathematics, IITB
o A 3 day CEP course on “Applied Mechatronics”
o 3rd meeting-cum-workshop of SIG-MDO
o International Conference “MSO-DMES 2003”
It is to be mentioned here that some of the short-term courses were specially created
with requirements of DRDO in mind. Further, opinions have been expressed that the
brainstorming sessions organized by CASDE, are models that need to be perpetuated.
While, CASDE has spent Rs. 25 Lakhs over a period of 5 years, core and associate
faculty and staff of CASDE have expended substantial time & effort in organizing
these events. CASDE believes that many DRDO laboratories and other user agencies
as a whole have benefitted from the Awareness Creation Element, for which
CASDE has been taking initiative, and such a trend should continue with support
from ARDB. The recurring support needed for Awareness Creation Element is Rs. 5
Lakhs per annum, without any time limit.
Proposed Financial Models for CASDE in Phase-II (from April 2004)
The previous section has presented in nutshell, the achievements of CASDE during its phase-
I as well as how CASDE needs to be sustained over the next 5 years, in order to guarantee
long term sustenance and growth for achieving worldwide visibility. Based on the discussions
presented in previous section and the sentiments expressed by the members of JPC during its
4th meeting on September 12th, CASDE proposes four alternate financial models for
consideration, and approval of any one of them, by the JPC of CASDE.
5
Model-A: Full Funding from ARDB for a Period of 5 years since April 2004
Under this model, a total of Rs. 242 Lakhs are sought from ARDB, for fully supporting (1)
Centre Element, (2) Project Elements and (3) Awareness Creation Element for a further
period of 5 years since April 2004.

Project Elements - Rs. 100 Lakhs
Awareness Creation Element - Rs. 25.0 Lakhs
High End Computing Power - Rs. 20.0 Lakhs
Over Heads - Rs. 22.0 Lakhs
Under this model, CASDE would work closely with DRDO laboratories and other user
agencies as a technology enabler, to achieve SDE objectives. In addition, CASDE would
strive for its own recognition on a global level.
However, a suitable tapering strategy would be needed at the end of Phase-II (i.e. by March
2008), for continuance of CASDE beyond 2009.

In this case, from April 2005 onwards, CASDE would put up its various activities to DRDO
laboratories and other user agencies for financial support. Only those activities would be
undertaken by CASDE, which find sponsors.

In this case, from April 2005 onwards, CASDE would put up its various activities to DRDO
laboratories and other user agencies for financial support. Only those activities would be
undertaken by CASDE, which find sponsors.
In addition, from April 2006 onwards, CASDE would only announce various courses and
seminars and depending on which of these get funding from DRDO laboratories and other
user agencies, only those would be undertaken by CASDE at no cost. Further, the cost of
time & effort put in by the CASDE core faculty, associate faculty and staff would also be
recovered from sponsoring agencies.
8
Model-D Full Funding from ARDB for a Period of 2 years since April 2004 and no
further funding from ARDB from April 2006 onwards
Under this model, a total of Rs. 110 Lakhs are sought from ARDB, for fully supporting the
Centre Element, the Project Elements and Awareness Creation Element for first two
years only. It may be noted that Model-D is what was proposed by CASDE as Phase-II, and
was discussed by the members of the JPC, in its 4th meeting on September 12th 2003.

High End Computing Power - Rs. 20.0 Lakhs
Over Heads - Rs. 10.0 Lakhs
In this case, from April 2006 onwards, CASDE would no longer be an ARDB Centre of
Excellence and this would be informed to the BOG IITB and ARDB, well in advance.
In addition, CASDE would start seeking support for its sustenance as well as for its various
activities, from DRDO laboratories and other user agencies, including private industry, well
before March 2006. The orientation and character of the CASDE will be decided by the
nature of funding received from a specific source, as well as availability and interest of core
and associate faculty.

Concluding Remarks
The broad objectives of CASDE in Phase-I were (1) establishment of M. Tech. specialization
in Systems Design & Engineering, (2) setting up of IMSL and (3) carrying out of various
system level studies. It is believed that CASDE has been able to achieve these objectives, to
the satisfaction of DRDO/user agencies and also to its own satisfaction. In particular, CASDE
has revitalized the design as an educational discipline and rekindled interest among student
about hardware related projects. CASDE has also got together researchers within DRDO, and
outside of it, to brainstorm and initiate new scientific disciplines in this important area.
However, CASDE feels that the last 5 years of Phase-I are just the beginning and many
activities are in their infancy within CASDE, as well as in many DRDO laboratories and user
agencies. There is a perceived need to nurture and support CASDE by ARDB & other DRDO
agencies, for at least a further period of five years, starting April 2004 (when extended phase-
I will come to an end), which will provide the strength and visibility to CASDE, necessary
for its long term sustenance and steady growth.
ARDB has been generous with its support during phase-I and it is hoped that ARDB will
continue to extend its support to CASDE in its Phase-II, which is considered important for
consolidation of gains made during Phase-II and for achieving a position of strength.

APPENDIX-B: High-end Computational Resource Requirement to Support Research at
Centre for Aerospace Systems Design & Engineering and
Department of Aerospace Engineering, Indian Institute of Technology Bombay
Computational resources have been critical for research in several areas concerning
Department of Aerospace Engineering, IIT Bombay. CFD, FEM, Design Optimization and
flight dynamic simulations are some of these areas. Presently the department is planning
activities in 2 areas that will require substantial computing power.
CFD Based Optimization
CFD is recognized as a CPU intensive activity. If CFD enters the optimization loop problems
compound. Bringing CFD into optimization loop requires research into many areas. Several
exploratory studies have been undertaken in CASDE during the last 2 years. Sequential RSM,
Design & Analysis of Computer Experiments, Automatic Differentiation for FORtran
(ADIFOR) are some of these studies. In addition, two focused research thrusts in
optimization using CFD are planned, as follows.
Optimization of a 3D-Duct Using NS: 3-D Duct is a realistic geometry with immense
practical importance. This will be a show case problem that will demonstrate a capability and
will accrue significant experience.
Optimization of a Hypersonic Nozzle using Euler: This is computationally relatively less
intensive than the 3D-Duct problem. A thorough investigation, and not just a showcase run, is
planned. Hence it will require several different exploratory studies.
Following is a list of faculty and Research Staff working in this area,
Prof. A.G. Marathe, CFD
Prof. P.M. Mujumdar. FEM, MDO
Prof. K Sudhakar. MDO, Aerodynamics
Prof. A. Chatterjee, CFD, CEM
Prof. S.K. Sane. RSM, System Optimization
Mr. A. Isaacs, RS & also PhD Scholar in MDO
Mr. D. Ghate, Dual Degree graduate in CFD from Aero., IITB
Computational Electro-Magnetics (CEM)
Presently a code for CEM based Finite Volume Time Domain (FVTD) has been developed
and applied to simple configurations. It is proposed that this be applied to more complex 3-D
geometries. A 3D-Duct is chosen as candidate geometry for this showcase problem. Faculty
members involved are; Prof. Chatterjee & Prof. Shevare.
Department of Aerospace Engineering continues to have a strong group working in CFD
areas like algorithms, solver and pre- & post-processing. The present computing power
(including the Linux cluster) available to this group has proved to be inadequate. This group
has also launched ambitious plans to expand activities to include; Hypersonic CFD including
non-equilibrium chemistry; Moving boundary & unsteady solvers.
12
This group consists of,
Prof. G.R. Shevare
Prof. J.C. Mandal
Prof. A. G. Marathe
Prof. A. Chatterjee
Conclusion
Department of Aerospace Engineering has initiated work in the area of Design
Optimization and MDO over the last 3 years
A cohesive and sizeable group has formed within the department
This group has steadily gained strengths and holds a position of leadership
nationally
Publications in this area have increased steadily in the past 2 years and will grow
further in number and importance.
Strong requirement for computing power exists
The group will gain considerable strength nationally and internationally with
augmentation of computing infrastructure.
Proposed steps to address this issue are;
Add 1 or 2 high-end Intel based IBM Machines with twin CPUs or better
immediately using IIT Bombay funding (This has since been done@).
Explore external funding that can set up better facilities within next 1 to 2 year
Plan for a superior facilities once the funding is identified. The plan should cater
for efficient exploitation of resources by inducting the correct mix of servers,
access stations and graphics workstations injected in a phased manner to
synchronize with growth of requirements.
