Mr.Vinoth Kumar (GUIDE)
The principal objective of this project is to test the feasibility of a subsonic RAMJET engine. The engine is to be first designed and fabricated using stainless steel and ducted fans.Then the feasibility of the engine is to be tested by varying the various parameters.These parameters include the inlet mach number from the ducted fan.The other parameters are to be decided once the engine has been fabricated.
A ramjet is designed around its inlet. An object moving at high speed through air generates a high pressure region upstream. A ramjet uses this high pressure in front of the engine to force air through the tube, where it is heated by combusting some of it with fuel. It is then passed through a nozzle to accelerate it to supersonic speeds. This acceleration gives the ramjet forward thrust.
To achieve the goal of designing and fabricating a working model of a subsonic RAMJET engine and experiment on its feasibility in the given time frame under the guidance of a project guide.
The ground work is done in this phase.It includes the various calculations required to find out the specifications of the subsonic RAMJET engine.

DESIGN AND FABRICATION
The designing is to be done using CATIA software and fabrication of the subsonic RAMJET engine is to be carried out according to the specifications in this particular phase.
SUBSONIC RAMJET ENGINE
The subsonic RAMJET engine is a specialized form of RAMJET engine.The inlet is less than Mach 1.The working of the engine is similar to that of a typical RAMJET engine.
The engine is tested first for working conditions.Then various parameters are to
be varied and a parametric study is to be
carried out on the subsonic RAMJET engine.
