Boundary Layer Characteristics on a Tiltrotor Blade Model
… layer characteristics at the trailing edge of a tiltrotor blade model were measured using a flattened pitot probe and a single hot wire. The blade was mounted in Virginia Tech Stability Wind tunnel stationary on a turntable on the wind tunnel's upper wall with the tip pointing down. The …

Analysis of fountain effect for tiltrotor configuration using computational fluid simulation and experimental method
The study involves a tiltrotor’s wing/rotor configuration design to properly test the model in both hover flight condition and crosswind condition replicated in the wind tunnel. To record data, a subsonic wind tunnel was utilized to test the wing/rotor configuration in different conditions of …

Design, Development, and Testing of a Conformal Power Control Interface for Thrust Vectoring Aircraft
… five years, a new power control inceptor for tiltrotor aircraft, known as the Rotational Throttle Interface (RTI) was designed and built. Prior to the RTI, no tiltrotor inceptor had been able to simultaneously indicate both the direction and magnitude of thrust conformally. The purpose of the …

Aerodynamic Trade Study of Compound Helicopter Concepts
… Models of a conventional helicopter and of a tiltrotor were implemented as well, and the results used as a datum for comparison. In each case, the predictive capabilities of the model were validated using flight test data. The comparisons were conducted on the basis of equal aircraft gross …
