The primary study of 3-point calculation method for the flush air data system

Abstract

The basic design standard is given for the flush air data system. In order to meet the requrement to study the atmosphere feeling system for the new generation aviation and aerospace vehicles in this paper. The initial results of "3-point calculation method" are presented, adopting the theory analysis and wind tunnel test method. The results indicated that the study design is reasonable. The pressure distribution trends of the model ex-fuselage of vehicles is reasonable. The values can be belived under the conditions of experiment. 3-point calculation method for the flush air data system is practical for engineering purposes. It can provide reference proofs for the atmosphere feeling system.
