Abstract

Bench Tests for Exhaust Gas Temperature Distribution in an Aircraft Piston Engine with and without a Turbocharger

Highlights

The authors of the reports [1, 2] claim that aviation is currently one of the fastest growing industries in the world
The introduction of turbocharging causes an increase in exhaust gas temperatures before the turbocharger by an average of 12%, with this increase being greater for operating points of higher inlet manifold pressure
The following conclusions can be drawn from the temperature distribution in the exhaust manifold of the Rotax 912 aircraft engine for the turbocharged and non-turbocharged exhaust system configurations:

Summary

Introduction

The authors of the reports [1, 2] claim that aviation is currently one of the fastest growing industries in the world. The introduction of turbocharging causes an increase in exhaust gas temperatures before the turbocharger by an average of 12%, with this increase being greater for operating points of higher inlet manifold pressure. The tests were carried out at 23 steady state engine operating points in the intake manifold with 28÷98 kPa of air pressure in the manifold and a speed range of 2000÷4600 RPM (Fig. 9).
