Due to their high fuel consumption, afterburners are usually used as little as possible; a notable exception is the Pratt & Whitney J58 engine used in the SR-71 Blackbird.
A very sophisticated conical intake was featured on the SR-71's Pratt & Whitney J58s that could move a conical spike fore and aft within the engine nacelle, preventing the shockwave formed on the spike from entering the engine and stalling the engine, while keeping it close enough to give good compression.

The patents for the fuel cell were licensed by Pratt and Whitney as part of a successful bid to provide electrical power for Project Apollo.
Bombardier Ltd, at the Plattsburg, N.Y. plant where the Acela was produced, developed a prototype (JetTrain) which combined a Pratt & Whitney Canada PW100 gas turbine and a diesel engine with a single gearbox powering four traction motors identical to those in Acela.
Typical of this configuration are the long-established Honeywell TFE731, the Honeywell ALF 502/507, and the recent Pratt & Whitney PW1000G.
All early F-35s were to be powered by the Pratt & Whitney F135 but it was planned that engine contracts would be competitively tendered from Lot 6 onward.
The Galaxy was based on a new wider fuselage, attached to a strengthened Astra SPX wing with integrated winglets and modified high lift devices, powered by new 5,700 lb (25.3 kN) thrust Pratt & Whitney Canada PW306 turbofans, and with improved Pro Line 4 avionics and all-new interior.

In 1927 he became a research engineer at the Pratt & Whitney Aircraft Company and by 1944 was vice president of engineering for parent company United Aircraft Corporation.
This resolution, the Airmail Act of 1925 was signed into law on February 2, 1925, prompting many companies to venture into the aviation field (e.g., Boeing, Douglas, and Pratt & Whitney).
Nike Ajax anti-aircraft missiles were located at HA-36 to protect Hartford’s aircraft industry from Soviet bombers.
Water injection in the J57 produced extra power for takeoff but caused large amounts of unburned fuel to leave the engine in the exhaust, producing large amounts of black smoke which the subsequent aircraft would also have to go through in order to take off successfully.
Her work can be found in corporate collections, including Lavalin, Pratt & Whitney, Shell Canada, and Selection du Reader’s Digest.
The RD-180 engine, developed with Pratt & Whitney Rocketdyne through the RD AMROSS partnership, is a direct descendant of the RD-170 line, and is used as the propulsion system for the first stage of Atlas V.
These products are formulated and approved against the relevant military specifications and validated by major aerospace Original Equipment Manufacturers (Airbus, Boeing, Eurocopter, CFM International, International Aero Engines V2500, Rolls-Royce, Pratt & Whitney…).
Francis A. Pratt (1827–1902), was a Connecticut mechanical engineer, inventor, and founder of Pratt & Whitney.
It currently manufactures parts and performs maintenance, repair and overhaul operations on jet, turbo shaft and turboprop engines under license from Rolls-Royce and Honeywell; it also holds Long Term Agreements from other Original Equipment Manufacturers, including Pratt & Whitney, Pratt & Whitney Canada and Micro turbo, whose engines power civil and military aircraft and helicopters.
: Powered by two Pratt & Whitney R-2180 radial engines and room for 43 troops, one built later converted to a YH-16B.

It was powered by four Pratt & Whitney R-4360-20WA engines.
An unusual example of the turboshaft principle is the Pratt & Whitney F135-PW-600 engine for the STOVL F-35B - in conventional mode it operates as a turbofan, but when powering the LiftFan, it switches partially to turboshaft mode to send power forward through a shaft (like a turboprop) and partially to turbojet mode to continue to send thrust to the rear nozzle.
The school was named for William T. Dwyer, former vice president of Pratt & Whitney's Government Products Division and a community leader in Palm Beach County.
After the Navy took delivery of the aircraft, they installed a rival company's engine, the Pratt & Whitney R-1340 radial.
