Abstract: An Energy State Awareness System that alerts the pilot of an aircraft during the climb, cruise and descent phases of a flight of low airspeed conditions, and during the Approach/Landing and Go-Around phases of flight when airspeed has deviated from a pre-determined reference airspeed that is considered “Stable” for the flight conditions. In order to determine the degree of deviation, the system monitors some of various readily available signals representative of flight parameters and of the aircraft's configuration such as true airspeed, weight, flap position, center of gravity and normal load factor—nz. Some signals are used directly, others are used as inputs to internal algorithms that compute the data necessary to determine the magnitude of the deviations.

Abstract: An expanded field of view visual display concept capable of conducting credible close-in or within visual range (WVR) air-to-air combat from a single computer graphics display screen. By use of the invention, the visual scene content that normally exists outside and around the cockpit of a fighter aircraft can be condensed onto a single CRT screen or video projection screen in such a manner that pilots have good situational awareness, even in close-in-combat, and can fly credible air combat. An expanded field of view visual display is created, referred to as target coordinate display (TCD), capable of conducting credible close-in simulated air combat from a single CRT display or video projection screen. The display handles multiple aircraft, shows friendly aircraft formations, is usable in real time, shows weapon release information, is easily adapted to by pilots, and yields credible air combat simulation results.

Abstract: A method of extending the maneuver, performance and flight safety of a specific fighter aircraft, namely, the F-16, is disclosed. In accordance with the method, a portion of the forebody strakes on the original aircraft which extend along each side of the fuselage to the front of the cockpit are eliminated, with a small leading edge cap capping the leading edge just forward of the structural bulkhead at the aft end of the cockpit. While the method involves the removal and replacement of skin panels, access doors and various frame members adjacent the cockpit, as well as the rerouting of one or more wire bundles, no major structural changes are required, and the modification may be made utilizing ordinary maintenance and repair procedures. The net result of the modification is to shift the center of pressure which acts on the forebody aft, thereby eliminating the deep stall characteristics of the aircraft.

Abstract: An aircraft nose and forebody shaped to produce relatively ideal vortex patterns which will provide improved static directional stability of the aircraft in the stall angle of attack region and above. The nose is shaped from its forwardmost tip with a broad, flattened lateral cross section having relatively sharp edges extending around each lateral surface, blending rearwardly to a radius approximately midway between the top and bottom surfaces of the forebody in the region where separation of the vortices is desired.
