Abstract

Research and calculation of aircraft performance is very important especially for small aircraft when encountering gusts of vicious winds.  The quality of flight depends not only on the aerodynamic characteristics of the aircraft itself but also on other factors such as control effects, turbulence of the external environment such as temperature, pressure, air turbulence, etc. Traversal wind is also a form of noise that deflects the air flow, converting the symmetrical flow around the aircraft into an asymmetric flow, so the calculation of the determination of aerodynamic characteristics also loses symmetry, i.e., It is necessary to make specific calculations for all parts of the aircraft even though conventional aircraft are shaped as symmetrical.

The objective of this paper is to calculate the aerodynamic characteristics of the L39 training aircraft being used by the Vietnam Air Force in flight training when the aircraft is exposed to traversal winds and to calculate the safety limit during takeoff and landing.
