Design and Performance Analysis of Single Inlet Multiple Outlet Jet Nozzle with Thrust Vector Control

Abstract

Today, thrust vectoring has become a very important research subject which can dramatically change the way aircraft maneuver and its performance. This paper tries to present a unique approach to this topic by highlighting a concept defined as Single Inlet Multiple Outlet (SIMO) in detail. This can be explained by having multiple nozzles for exhaust purpose than those conventional one or two nozzles as we know of presently. This idea may yet not be able to apply directly to VTOL (Vertical Takeoff & Landing), but can be applied very well to change thrust direction of the aircraft effectively including thrust reversal and hence reducing the dependability on the primary control surface to great extent. These nozzles can be made to work in tandem with primary control surfaces so that, in case of failure of primary control surfaces occur, the aircraft can still be maneuvered and saved thereby avoiding loss of millions of dollar worth of property, aircraft and most important pilot’s life.
