Abstract:

Fighter's tactical performance is affected by static source error.It is one of the important problems in aircraft design air data computer research and flight test. Also it is a comprehensive frontier scientific subject. With the development of avionics,computer technique, wind tunnel technique and flight testing equipment the static source error correction has entered into a new phase accordingly.It is divided into two ways outside compensation by pneumatic compensated pitot tube and inside compensation,residual error is compensated by air date computer.Therefore the compensated accuracy may be very high.This paper analyses static source error,its effective factor and compensation method as viewed from engineering.
