摘要：

Sizing and performance analysis of the downscaled tiltrotor are presented in which simple codes based on blade element and momentum theory were used. The conversion corridor of the tiltrotor was predicted and the nacelle tilt angle and air speed were compared with flight-test results. The performance analysis code named SPAC (Smart UAV Performance Code) was developed and used for the performance estimation. The code has a capability to calculate the three modes of tiltrotor flight: hover, transition, and cruise. The hovering performance of the 1/2.5-scale proprotor was calculated and the result was used for investigation of the hovering capability as well as for the initial sizing of the rotor. The ground and flight tests were conducted using rate stability augmentation system and attitude stability and control augmentation system feedback. The flight test verified that the stability and control augmentation algorithm worked well in the flight control software.
