Front-mounted air-to-air intercooler Top-mounted air-to-liquid intercooler (the silver cuboid-shaped part) on a BMW S55 turbocharged engine. An intercooler is a heat exchanger used to cool a gas after compression. [1] Often found in turbocharged engines, intercoolers are also used in air compressors, air conditioners, refrigeration and gas ...
The turbine itself was designed primarily by Rolls-Royce with significant marine engineering and test facility input from DCN, with Northrop Grumman responsible for the intercooler, the recuperator and system integration. [1] [2] WR-21 development draws heavily on the technology of the successful Rolls-Royce RB211 and Trent families of gas ...
The Junkers Jumo 213 was a World War II-era V-12 liquid-cooled aircraft engine, a development of Junkers Motoren's earlier design, the Jumo 211.The design added two features, a pressurized cooling system that required considerably less cooling fluid which allowed the engine to be built smaller and lighter, and a number of improvements that allowed it to run at higher RPM.
Generally these engines all have the slanted intercooler. Engines from the STI RAs received the upgraded Shim-Under-bucket style lifters unlike the normal HLA buckets the WRX & the WRX STI had. These engines also feature STI factory 8.5:1 forged pistons, lighter valves, the intake valves are marked INKO and the exhaust valves are marked EXKO.
A hush house is an enclosed, noise-suppressed facility used for testing aircraft systems, including propulsion, mechanics, electronics, pneumatics, and others. [1] Installed or uninstalled jet engines can be run under actual load conditions.
The DARPA contract is to test the Sabre engine's pre-cooler heat exchanger (HTX). Construction of the test facilities and test articles began in 2018 with testing focusing on running the HTX at temperatures simulating air coming through a subsonic intake travelling at Mach 5 or around 1,800 °F (1,000 °C) beginning in 2019.

A precooled jet engine is a concept that enables jet engines with turbomachinery, as opposed to ramjets, to be used at high speeds.Precooling restores some or all of the performance degradation of the engine compressor (by preventing rotating stall/choking/reduced flow), as well as that of the complete gas generator (by maintaining a significant combustor temperature rise within a fixed ...
The Allison V-1710 aircraft engine designed and produced by the Allison Engine Company was the only US-developed V-12 liquid-cooled engine to see service during World War II. Versions with a turbocharger gave excellent performance at high altitude in the twin-engined Lockheed P-38 Lightning , and turbo-superchargers were fitted to experimental ...
