T&E 4112 Helicopter Performance Flight Testing II

Course Description

This course is a continuation of the intensive overview of theory and flight-test techniques employed during the evaluation of helicopter performance characteristics.  Emphasis is placed on turboshaft engine performance, climb and descent performance, takeoff and landing performance, and the performance characteristics of multi-engine helicopters.  (Prerequisite: Successful completion of T&E 4111).

Anticipated Student Academic Outcomes

Upon successful completion of this course of instruction, the student will have a basic understanding of performance flight test theory, procedures, techniques, and data analysis of the topics covered.  He/she will:

Be familiar with
1.  FADEC testing.

2.  Turbine engine theory & test procedures.
3.  Transonic aerodynamics principles.
4.  Autorotational descent performance.

5.  Climb and descent performance theory and test methods.
6.  Take-off/landing performance theory and test methods.
7.  Height-velocity theory and test methods.
8.  Level flight performance theory and test methods.
9.  How to predict significant airspeeds from performance data.
10.  The effects of engine failure.
