A propulsion system for an aircraft includes: (1) an engine configured to generate a mass flow, (2) a nozzle having a pathway having a throat and a trailing edge, the throat or the trailing edge being configured to enlarge and contract, (3) a deployable obstructer disposed in the nozzle...
An all-electric propulsion system relies solely on the battery or fuel cell as energy source, while the hybrid-electric propulsion system relies on both battery or fuel cells and jet-fuel- based gas turbine engines. A turbo-electric configuration is based on the combination of a gas turbine ...
During the initial design phase of any aerospace vehicle, the propulsion system is the key to achieving the mission requirements for payload, range, speed, and altitude. Propulsion systems, classified as an engine or a rocket motor, account for nearly all means of vehicle propulsion. In special ...
aircraft to realize strong stealth characteristics. Based on the layout characteristics within a confined space, a series of double serpentine nozzles with spanwise offsets are established. Using computational fluid dynamics and...
A propulsion system in the context of computer science refers to the combination of an engine and a surface propeller that is used to drive an unmanned aircraft (UA) forward. The engine, which is typically electrically driven, powers the propeller, allowing the UA to move efficiently. The prop...
Aircraft Propulsion is an engineering textbook written for students in aerospace and mechanical engineering. The book covers aircraft gas turbine engine and rocket propulsion from its basic principles to more advanced treatments in engine components. Propulsion system integration with aircraft plays an impor...
The aerodynamic propulsion system has an aerodynamic lifting body (A), e.g. wing, which is fastened in an enclosing channel (Ak) and produces pressure of a gas (PF). A current develops due to pressure of gas goes through the enclosing channel and cause a buoyancy force at aerodynamic lift...

The aircraft propulsion system consists of two sets of rotors or propellors which rotate about two intersecting orthogonal axes, thereby giving lift and forward propulsion. The sets are geared together so that they rotate at the same angular speed to avoid collision of rotor blades, and the aerody...
