| Summary: | (AOA) flight and rapid nose-pointing are now realities with a post-stall fighter. Comparison to Valasek and Downing's aircraft state during close-in combat. As complements to and onset rate axial agility metrics are acceptable and precisely change from its present state to a desired new as incorporating the newly acquired Agile-VU visualization between energy levels. The power loss rate test is modified characteristics, maneuvering in the 1-3 second time scale, of conventional fighter aircraft agility simulations is done for conventional performance measures of merit, agility metrics describe post-stall agility and performance improvements due descriptors of an aircraft's ability to rapidly transition Development of post-stall capable aircraft has enhanced the due to thrust vectoring are highlighted. The power loss rate each axis of agility tests, and the performance improvements for their effectiveness in describing transient agility generation and maintenance during a pitch maneuver. High and IA to describe an aircraft's balance of maximum load factor incapable of comprehensively describing the rapid changes in loop agility maneuvers on the fixed-base simulator for post- low AOA lateral agility tests also show improved roll maneuvering capabilities. A batch simulation model of the metric. Longitudinal nose pointing metrics effectively metrics maneuver is recommended as a post-stall axial agility open-loop longitudinal, lateral, and axial agility metrics performance about the velocity vector. A high AOA loaded pitch impulse metric, is developed and simulated on the X-3 pitch rate metrics. A new flight path agility measure, the post-stall axial agility metric. Longitudinal nose pointing program with metric research and flying recommended closed- provide a more complete description of an aircraft's rapid research of agility, the ability of an aircraft to quickly RockwelVMBB X-31A aircraft is used to evaluate recommended roll metric is developed using the integral of the velocity stall agility evaluation. state, and its measurement. Controlled high angle of attack the X-31A batch simulation Version-120 is recommended as well thrust vectoring. Traditional measures of merit are to create induced drag and maximize power loss rate. The to include a rapid pitch up maneuver and evaluate the ability to thrust vectoring with the maximum, minimum, and average vector roll rate as the angle of interest. Acquisition of |
