Abstract

The objective of this work is to analyze the aerodynamic response of SARAS transport aircraft to a gust condition. A rigid airframe is assumed. The increments in load factors due to vertical gust are calculated for gust gradient distances varying from 30 to 350ft as per Federal Aviation Requirements (FAR) specifications. The variations in the angles of attack due to gust and airplane motion are also studied. This tuned discrete gust analysis includes the effects of unsteady aerodynamics. The analysis is performed considering the aircraft plunge degree of motion (tail-off). The effect of damping due to the tail contribution is also studied.

SARAS飞机离散阵风响应分析

本文的目的是分析SARAS运输机在阵风条件下的气动响应。假设机身是刚性的。根据联邦航空要求(FAR)规范，垂直阵风引起的负载系数增量是根据30至350英尺的阵风梯度距离计算的。还研究了阵风和飞机运动对迎角的影响。这种调谐离散阵风分析包括了非定常空气动力学的影响。分析考虑了飞机的俯冲运动度(尾距)。研究了尾翼对阻尼的影响。
