Aero 321 Planes

Bell P-39 Airacobra

S&C Characteristic: midengine airplane, neutrally stable. Engine behind, propellor in front, drive shaft below, the pilot

Messerschmitt Me 509

S&C Characteristic: midengine airplane. neutrally stable. Influenced by P-39

Yokosuka R2Y1

S&C Characteristic: midengine airplane. neutrally stable. Influenced by P-39

Lockheed F-22 Raptor

S&C Characteristic: Has a horizontal tail, but originally did not need it because it had thrust vectoring

Chengdu J-20 Mighty Dragon

S&C Characteristic: Horizontal tail, influenced by F-22

Northrop YB-49 Flying Wing

S&C Characteristic: No H-stab, no fuselage, 8 jet engines, statically stable, bad volumetric

Lockheed SR-71 Blackbird

S&C Characteristic: V-tail is canted inward. low observable. loses some stability. mach 3.2

North American XB-70 Valkyrie

S&C Characteristic: wing tips can hinge down. canards, delta wing, 6 side-by-side engines. 'big fast bomber'

Boeing B-52H Stratofortress

S&C Characteristic: Fuel sloshing caused one to crash (fuel is in the wing so acceleration pushed to the back and changed center of mass so they pitched up). they added windage trays to mitigate

Convair B-36D Peacemaker

Produced in FW, TX; 6 gas-engines, 4 turbo-engines

Oblique Flying Wing

Asymmetry caused inertial coupling; plane only ever a concept due to being impractical and commercial safety issues (unable to park at gates, safety issues with exists and fuel location, etc.)

Blohm & Voss BV 141 B-0

Asymmetric; observation/reconnaissance aircraft with observation pod mounted on wing for increased visibility; H. Tail cut short to increase range of fire for machine gun on rear

North American F-100 Super Sabre

Inertial coupling due to unbalanced inertias

Convair F-106 Delta Dart

Very high inertial coupling made flying very difficult; huge discrepancy in principal inertias so unbalanced; tendency to resist rotation

Grumman F11F-1 Tiger

N/A

Douglas X-3 Stilletto

Very large imbalance in principle inertias; very high inertia coupling due to I_xx-I_yy being very large

Boeing V-22 Osprey Tiltrotor

Very large gyroscopic effects that vary based on flight configuration (-h_z when vtol and h_x when forward flight); Must land in VTOL config due to rotors being too large; very hard to control

Junkers Ju 52

Toe-out angle helps in the event of an engine-out scenario by reducing the amount of rudder required to counteract the imbalance in moment due to propulsion

McDonnell Douglas MD-80

Engines angled upwards to reduce intake spillage due to downwash effects. Decreased drag during cruise conditions.
