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.
