Investigation of thermal interactions between the exhaust jet and airplane skin in small aircrafts

Abstract

An advanced numerical model of the exhaust jet and its thermal interaction with the aircraft body (fuselage, wings and flaps) was developed in this paper and then applied for investigations of two aircraft prototypes in different configurations. Both airplanes were equipped with new turboprop engines. Therefore their new exhaust systems should be carefully analysed. The first of the investigated airplanes in the tractor configuration with one engine located in the fuselage (TR1) had the exhaust outlets below the nacelle. The second one was also in the tractor configuration with two engines located on the wings (TR2) and had the exhaust outlets on the rear part of the nacelles. The aim of the performed analyses was to check if the exhaust systems were properly designed and streams of hot exhaust gases would not contribute to airplane cover softening or even melting for the most adverse flight conditions.
