The performance of a conceptual 18,000-lb (8200-kg) vertical attitude takeoff and landing fighter aircraft is presented. The single-seat aircraft is designed around a single F100 turbofan. Contemporary avionics and materials technologies are assumed. The design payload includes an M61 cannon with ammunition and four Dogfight missiles. No compromises for mission capabilities, other than air combat, exist in the design. The fighter has a combat radius of 308 nm (570 km) with a maximum level speed in excess of Mach 2 at altitude. Range, turning, and specific excess energy performance are presented. Weight and range performance penalties for the inclusion of conventional landing gear, a rotating cockpit, and a multi-engine design are summarized. (Author).

A Study of five jet vertical takeoff and landing fighter concepts was made considering height and attitude control, ground effect, ingestion losses, control bleed effects, installation losses, component weights, and short takeoff performance. A fixed gross weight of 35,000 pounds was assumed for each of the following concepts studied: Lift Plus Lift/Cruise; Lift/Cruise Plus Remote Burner; Lift/Cruise (bleed air for control); Vertical Attitude Takeoff and Landing, and Tilt Wing. Since total mission performance was not included in the study, no conclusion as to the 'best' concept is made, but rather some of the mission/concept tradeoffs are presented. (Author).

Previous studies have shown the vertical attitude takeoff and landing (VATOL) concept to have the least penalty for achieving vertical takeoff and landing capability. In this study, features are examined that should be included in a research aircraft to explore, develop, and demonstrate the full opertional feasibility of the VATOL concept. Conceptual arrangements of two sizes of research aircraft designed around existing engines are presented, including the research and development needs.

The possibility of modifying an existing fighter aircraft to give it V/STOL capability and of incorporating a V/STOL control system that could also be used in conventional flight to improve the aircraft's combat maneuverability is examined. The study indicates that the F-18 could be given a V/STOL capability using either the lift plus lift-cruise or the vertical attitude take off and landing (VATOL) concept. The lift-cruise plus remote burner concept does not appear to be compatible with the F-18 airframe. The ADEN nozzle concept currently under development, with some modification, could be used on either the lift plus lift-cruise or the VATOL concepts to vector the cruise engine thrust and thereby augment the conventional controls for improved high angle of attack combat maneuverability.
