The paper gives an overview of the propulsion content of the programs at the undergraduate and postgraduate levels, as offered to students in both Mechanical and Aerospace Engineering.

The requirements of engine test cells and propulsion laboratories for propulsion education will be discussed. A typical versatile propulsion laboratory set-up for testing full-scale aircraft reciprocating engines, gas turbines, as well as small-scale rocket motors will also be presented. ...There are a variety of propulsion packages available for general aviation aircraft including reciprocating engines, small gas turbines, and rotary engines. ...In future, electrical propulsion will be a major contender in this market. The importance of general aviation propulsion education for aeronautical engineers will be addressed.

Incorporation of an advanced technology, high-speed turboprop propulsion system into future air transports can achieve significant reductions in operating costs through large reductions in fuel consumption. ...The advantages of the propfan aircraft, in light of ever-increasing fuel shortages and fuel cost increases, have resulted in several NASA-sponsored research programs to verify propulsion performance and develop the required technology base. Continuation and escalation of these activities must be accomplished to ensure incorporation of the propfan into the next generation of commercial air transports.

This paper describes the status of the compact multimission aircraft propulsion simulator (CMAPS) technology. Three CMAPS units have accumulated a total of 340 hr during approximately 1-1/2 yr of static and wind-tunnel testing.

It included several courses directly related to aircraft propulsion such as: Advanced Turbomachinery and Propulsion, Gas Turbine Design, Fuel Control Systems for Combustion Engines, Vibration Problems in Rotating Machinery, etc. ...The Montreal area has a well developed aerospace industry with a continuous need for young engineers broadly educated in aircraft propulsion.

The demanding performance requirements of advanced turbine-powered tactical aircraft have made it important to understand and accurately evaluate the propulsion system/airframe interactions. The turbine engine multi-mission propulsion simulator offers the potential for accurate evaluation of these interactions by permitting the simultaneous simulation of inlet/airframe/nozzle flowfields on a single wind tunnel model.

Engine cycle designs for ultra-high bypass ratio, constant volume combustor, and recuperated propulsion cycles are described, with a discussion of integration challenges within the airframe.

In the present market, multiple sophisticate and expensive Thrust Test Rigs for Brushless Motors (BLDC Motor) are available making it impossible to conduct such thrust analysis on a regular and cost effective basis. Moreover the present test rigs are incapable to measure high Thrust values. This needs specialized thrust testing rig which is more expensive. This paper aims at Design & Development of the Small Scale Test Rig Setup for measurement of the thrust of any Brushless DC motor and helps in refining the Selection of motor and propeller. This is a set up based on cost efficiency factor to implement such rigs, test and for comparing the static thrust produced by the BLDC motor. The fairly simple construction contains a weighing machine, a Tachometer and a Wattmeter to measure the Thrust, RPM and the Current Drawn respectively, and provide comprehensive, accurate and efficient data coming from the BLDC Motor including the Propeller and Electronic Speed Control (ESC).
