Abstract

A numerical analysis was peformed for the supersonic aircraft with variable pitch thrust vector nozzle. Based on the requirement of the mixed turbofan engine of the supersonic aircraft, two dimensional thrust vector nozzle with variable pitch angle was designed. To investigate the effect of the thrust vectoring nozzle, the numerical analysis was conducted by using Fluent under the several pitch deflection angle.

초음속 항공기에서 피치 편향이 가능한 추력편향 노즐에 대한 해석적 연구를 수행하였다. 초음속 항공기의 비행조건에서 터보팬 엔진의 기본성능을 도출하였으며, 이를 바탕으로 이차원형태의 피치 편향이 가능한 추력편향 노즐을 설계하였다. 상용 해석프로그램인 Fluent 를 이용하여 축소확대 노즐에 대한 기본 유동특성을 파악하고, 피치 추력편향시의 유동특성과 비교하였다.
