INVESTIGATION OF A VARIABLE AREA SCROLL FOR POWER TRANSFER IN TIP TURBINE LIFT FAN SYSTEMS

Abstract

Demonstration tests and analog simulations were performed for the variable area scroll power transfer applicable for thrust control of tip turbine driven lift fans. The tip turbine driven lift fan used the lightweight LF2 rotor. Control response rates of 0.31 second for roll control and 0.10 second for height control were demonstrated. The jazzer, an anticipatory device, improved the response to about one-half the original level. Aerodynamic performance of the system met or exceeded objective levels.
