MANE 4230: Fixed Wing Design
Spring Semester 2013
May 2 and 7 or 7 and 10
(Or the previous week if not using reading days)
The FDR summary should include:
1. Brief review of the PDR results.
2. Airplane’s 3 views drawings including major dimensions and major items on the
airplane: fuselage with cockpit, passenger’s galley, and baggage compartment, wings,
engines, fuel tanks, tails/canard and control surfaces, landing gears.
3. Loads and Structure:
(a) Load analysis and n (load factor) vs. V (speed) diagrams for various airplane’s
weights and altitude of flight.
(b) Structural and strength analysis of the wings main beam: distribution of loads, shear
force, and bending moment along the beam and stress analysis.
(c) Structural and strength analysis of the tails/canard beams: distribution of loads, shear
force, and bending moment along the beams and stress analysis.
(d) A drawing of the airplanes main beams and frames.
(e) Aero-elastic divergence analysis of the wings and tails/canard.
4. Stability and Control
(a) Inertia properties of the airplane at various points of flight (Ix, Iy, Iz).
(b) Sizing and position of tails/canard.
(c) Sizing of flaps and control surfaces (elevators, rudder(s), ailerons).
(d) Stability derivatives of the airplane at take-off, cruise, and landing flight conditions.
(e) Flying qualities of airplane in 5 basic motions.
(a) Rate of climb analysis as function of altitude and speed (Mach number) for several
(b) Ceiling and optimal rate of climb and speed as function of altitude for various
(c) Envelopes of flight in h (altitude) vs. Mach number diagram for various weights.
(d) Flight manual for take-off, optimal climb, cruise, and landing.
6. Weight analysis (using chapter 15 in Raymer’s book).
7. Cost analysis (using chapter 18 in Raymer’s book).
