2. Shock diamond - Wikipedia

   en.wikipedia.org/wiki/Shock_diamond

   Shock diamonds are the bright areas seen in the exhaust of this statically mounted Pratt & Whitney J58 engine on full afterburner.. Shock diamonds (also known as Mach diamonds or thrust diamonds, and less commonly Mach disks) are a formation of standing wave patterns that appear in the supersonic exhaust plume of an aerospace propulsion system, such as a supersonic jet engine, rocket, ramjet ...

3. Aerospike engine - Wikipedia

   en.wikipedia.org/wiki/Aerospike_engine

   Intended for the small satellite launch market, it is designed to launch satellites into low-Earth orbit (LEO) at a price of US$8–9 million, much lower than with conventional launchers. [ 8 ] Firefly Alpha 1.0 was designed to carry payloads of up to 400 kilograms (880 lb).

4. Specific impulse - Wikipedia

   en.wikipedia.org/wiki/Specific_impulse

   For example, LH 2 /LO 2 bipropellant produces higher I sp (due to higher chemical energy and lower exhaust molecular mass) but lower thrust than RP-1/LO 2 (due to higher density and propellant flow). In many cases, propulsion systems with very high specific impulse—some ion thrusters reach 25x-35x better I sp than chemical engines—produce ...

5. Variable cycle engine - Wikipedia

   en.wikipedia.org/wiki/Variable_cycle_engine

   The ejector reduces noise. It is deployed during take-off and approach. Turbofan exhaust gases send air into the ejector via an auxiliary air intake, thereby reducing the specific thrust/mean jet velocity of the final exhaust. The mixed-flow design is not particularly efficient at low speed, but is considerably simpler.

6. Otto cycle - Wikipedia

   en.wikipedia.org/wiki/Otto_cycle

   Through the combustion of fuel, heat is added in a constant volume (isochoric process) process (2-3), followed by an adiabatic expansion process power (3-4 and colored red) stroke. The cycle is closed by the exhaust (4-0 and colored blue) stroke, characterized by isochoric cooling and isobaric compression processes. Temperature-Entropy diagram
