Abstract:
Using a generalized simulation model, a moving-base simulation of a lift-fan

short takeoff/vertical landing fighter aircraft was conducted on the Vertical

Motion Simulator at Ames Research Center. Objectives of the experiment were to

(1)assess the effects of lift-fan propulsion system design features on aircraft

control during transition and vertical flight including integration of lift

fan/lift/cruise engine/aerodynamic controls and lift fan/lift/cruise engine

dynamic response, (2)evaluate pilot-vehicle interface with the control system

and head-up display including control modes fro low-speed operational tasks

and control mode/display integration, and (3)conduct operational evaluations of

this configuration during takeoff, transition, and landing similar to those

carried out previously the the Ames team for the mixed-flow, vectored thrust,

and augmentor-ejector concepts. Based on results of the simulation,

preliminary assessments of acceptable and borderline lift-fan and lift/cruise

engine thrust response characteristics were obtained. Maximum pitch, roll,

and yaw control power used during transition, however, and vertical landing

were documented. Control and display mode options were assessed for their

compatibility with a range of land-based and shipboard operations frrom takeoff

to cruise through transition back to hover and vertical landing. Flying

qualities were established for candidate control modes and displays for

instrument approaches and vertical landings aboard an LPH assault ship and

DD-963 destroyer. Test pilot and engineer teams from the Naval Air Warfare

Center, Boeing, Lockheed, McDonnell Douglas, and the British Defence Research

Agency participated in the program.
