An integrated and/or modular high-speed aircraft and method of design and manufacture. The aircraft can have a supersonic or near-sonic cruise Mach number. In one embodiment, the aircraft can include an aft body integrated with a delta wing and a rearwardly tapering fuselage to define a smooth forward-to-rear area distribution. A propulsion system, including an engine, inlet, and exhaust nozzle can be integrated into the aft body to be at least partially hidden behind the wing. In one embodiment, the entrance of the inlet can be positioned beneath the wing, and the exit of the nozzle can be positioned at or above the wing. An S-shaped inlet duct can deliver air to the aft-mounted, integrated engine. The aircraft can include aft-mounted elevators, wing-mounted elevons, and forward-mounted canards for pitch control. The construction of the aircraft can be modular to take advantage of commonalties between near-sonic and supersonic structures.

126 Fighter aircraft US465076 1995-06-05 US5636813A 1997-06-10 Richard Hardy; Frank D. Neumann; Dennis E. Ruzicka
A fighter aircraft achieves low aerodynamic drag and radar signature without sacrificing flight performance through a unique arrangement of the air inlets, the weapons bays, and the main landing gear. Separate main and auxiliary weapons bays permit a narrower fuselage than could be obtained with a single common bay. Also, the auxiliary weapons bays and the landing gear can be aligned outboard of the main weapons bay without needing to increase the length or width of the aircraft. The air intake ducts extend aft from each intake and curve upwardly and inwardly over the main weapons bay. The result of the design configuration is an aircraft of minimum fuselage width for optimal performance and which has a forward aspect reduced to the minimum necessary to accommodate the components that need forward visibilities, which translates to minimum aerodynamic drag and radar signature.

128 Supersonic airplane US477289 1983-03-21 US4828204A 1989-05-09 Gottfried O. Friebel
A twin-engine supersonic airplane having an arrow-shaped wing and an elongated fuselage extending approximately equally forward and rearward of the wing. The fuselage is configured for six passengers in a staggered two-abreast seating arrangement and for two pilots seated in tandem. A forebody section of the fuselage, which extends substantially forward of the wing, is of a specific geometric cross-sectional design, i.e., it is an egg-shaped cross section with opposite sidewalls sloping vertically inward in an upward direction. The sidewalls are only of a single curvature in a fore-and-aft direction, and this substantially flat surface has windows installed therein which have an optically flat surface in order that a minimum of visual distortion is produced due to thermal expansion during supersonic flight. Twin vertical stabilizers are spaced apart and each is mounted near a wing tip; and the stabilizers extend both vertically above and below the wing chord plane for functioning as wing tip end plates. Outboard of the vertical stabilizers is an auxiliary wing in coplanar alignment with the main wing and rotatably movable as a unit for lateral roll control and/or longitudinal pitch control of the airplane. The twin engines are spaced apart on either side of the fuselage, between the fuselage and the vertical stabilizers, and mounted to the undersurface of the wing.

A method of optimizing sections of a tail boom for a rotary wing aircraft, and also to a tail boom including such sections. The method comprises the step of creating a database characterizing standard sections for a tail boom that give precedence to minimizing a negative lift and/or to increasing a lateral force generated by the air stream from the main rotor of the aircraft flowing over the tail boom, a step of establishing looked-for aerodynamic and structural characteristics for said tail boom, and a step of defining the sections of the tail boom as a function of the standard sections and of the looked-for aerodynamic and structural characteristics. The tail boom as defined in this way optimizes the reduction in the negative lift and/or the increase in the lateral force generated by the air stream from the main rotor.
