Exhaust System
Published in Ahmed F. El-Sayed, Aircraft Propulsion and Gas Turbine Engines, 2017
Thrust vectoring is the ability of an aircraft or other vehicle to direct the thrust from its main engine(s) in a direction other than parallel to the vehicle’s longitudinal axis. Thrust vectoring is a key technology for current and future air vehicles. The primary challenge is to develop a multi-axis thrust-vectored exhaust nozzle, which can operate efficiently at all flight conditions while satisfying the design constraint of low cost, low weight, and minimum impact on radar cross-section signature. The technique was originally envisaged to provide upward vertical thrust as a means to give aircraft vertical takeoff and landing (VTOL) or short takeoff and landing (STOL) capability. Subsequently, it was realized that the use of vectored thrust in combat situations enabled an aircraft to perform various maneuvers and have better rates of climb not available to conventional-engined planes. Additionally, which is most important, thrust vectoring can control the aircraft by engine forces, even beyond its stall limit, i.e., during “impossible” post-stall (PS) maneuvers at extremely high-nose turn rates [11]. An interesting “definition” for thrust vectoring is introduced in Reference 12 as a maneuver effector that can be used to augment aerodynamic control moments throughout and beyond the conventional flight envelop. Rockets or rocket-powered aircraft can also use thrust vectoring. Examples of rockets and missiles that use thrust vectoring are the space shuttle SRB, S-300P, UGM-27 Polaris nuclear ballistic missile, and Swingfire small battlefield.
Water-jet propulsion system with vectorised thrust
Published in Petar Georgiev, C. Guedes Soares, Sustainable Development and Innovations in Marine Technologies, 2019
Thrust vectoring relates to the ability of an aircraft, missile, rocket, marine vessel, underwater object or other vehicle to change the direction of the thrust from its propulsion system and control elements in order to control the speed, depth, altitude or to maintain its stability. Reasons for application of vectoring thrust and control are as follows: to rotate the vehicle and change its attitude during flight; to change its depth in water; to control its dynamics; to maintain the altitude/the depth; to correct possible thrust misalignments; to change its trajectory of travel.
The system solution

Taking the static canting principle one step further, leads to active canting. This is sometimes referred to as thrust vectoring, and has been applied in full-scale military fighter aircraft for some time to aid rapid manoeuvrability.7
Design and analysis of Coanda effect nozzle with two independent streams
Published in International Journal of Ambient Energy, 2020
This project is all about dealing with thrust vectoring in vertical short take-off and landing (V/STOL). In general, thrust is the main force which helps in the motion of the aircraft. Thrust vectoring is the ability of the aircraft, rocket or other vehicle to manipulate the direction of the thrust from its engine or motor in order to control its attitude or angular velocity of the vehicle. In practice, for thrust vectoring, mechanical components are used. This project helps in removing the mechanical components for thrust vectoring.
