Rotary engines, often referred to as Wankel engines, are a type of internal combustion engine known for their unique rotor-based design. Unlike traditional piston engines, rotary engines have a rotating triangular rotor that completes three strokes (intake, compression, and exhaust) during one revolution. The exit of the exhaust gases in a rotary engine is not […]

piston engine is commonly found in internal combustion engines like those in cars or small aircraft. The total energy at the exit of a piston engine can be considered in terms of the kinetic energy of the exhaust gases as they leave the exhaust manifold. While it’s not as formally defined as in jet or

An aircraft propeller is an aerodynamic device which converts rotational energy into propulsive force creating thrust which is approximately perpendicular to its plane of rotation. The rotational energy can be produced by a piston or gas turbine engine or, in limited applications, by an electric motor.  A turboprop engine is a turbojet engine in which a

An aerospike engine is a type of rocket engine that uses a unique nozzle design called an aerospike to improve performance at different altitudes. In the context of an aerospike engine, the “nozzle exit” is the perimeter of the aerospike, which forms a bell-like shape. The total energy at the nozzle exit can be expressed

The Rolls-Royce Gnome is a turboshaft engine commonly used in various helicopters. In the context of a turboshaft engine, the term “nozzle exit” typically refers to the point where the exhaust gases exit the power turbine section. The total energy (E) at the nozzle exit can be expressed as: where, E is the Total Energy,

The TF34 is a military turbofan engine developed by General Electric. In the context of a jet engine like the TF34, the term “nozzle exit” refers to the point where the high-speed exhaust gases exit the engine’s nozzle. The total energy (E) at the nozzle exit can be expressed as: where, E is the Total

The Rolls-Royce Olympus 593 is a turbojet engine best known for powering the Concorde supersonic airliner. The Concorde was one of only two supersonic commercial passenger aircraft to have been operated commercially. The total energy (E) at the nozzle exit can be expressed as: where, E is the Total Energy, i.e sum of kinetic and

The RD-170 is a rocket engine developed in Russia and used on the Energia launch vehicle and the Zenit family of rockets. It’s a staged combustion cycle rocket engine that burns liquid oxygen and kerosene. The RD-170 engine operates on the principles of the staged combustion cycle, where propellants are partially burned in a pre-burner

The Saturn V rocket was a multistage launch vehicle used by NASA during the Apollo and Skylab programs to send astronauts to the Moon. The Saturn V had several stages, each powered by different rocket engines. The main engines of the Saturn V’s first stage (S-IC) were F-1 engines, and the second stage (S-II) was

In a cold gas propulsion rocket engine, the term “nozzle exit” refers to the point where the pressurized gas is expelled from the rocket nozzle to generate thrust. Unlike in combustion-based rocket engines, cold gas propulsion involves the release of compressed gas without combustion. The total energy (E) at the nozzle exit can be expressed
