For commercial jet aircraft the jet noise has reduced from the turbojet through bypass engines to turbofans as a result of a progressive reduction in propelling jet velocities. For example, the JT8D, a bypass engine, has a jet velocity of 400 m/s (1,450 ft/s) whereas the JT9D, a turbofan, has jet velocities of 300 m/s (885 ft/s) (cold) and 400 ...
The Volvo RM8 is a low-bypass afterburning turbofan jet engine developed for the Saab 37 Viggen fighter. An augmented bypass engine was required to give both better fuel consumption at cruise speeds and higher thrust boosting for its short take-off requirement than would be possible using a turbojet.
The F-35, however, is designed to be a family of three aircraft, a conventional take-off and landing (CTOL) fighter, a short take-off and vertical landing (STOVL) fighter, and a Catapult Assisted Take Off But Arrested Recovery (CATOBAR) fighter, each of which has a different unit price and slightly varying specifications in terms of fuel ...
The Owj (Persian: اوج, Apex) is an Iranian advanced turbojet engine developed by the Iran Aviation Industries Organization (IAIO). It is a reverse-engineered and enhanced version of the General Electric J85, showcasing Iran's ability to develop cutting-edge technology and its self-sufficiency in producing high-performance military engines, and demonstrating its capability to create advanced ...
YF119-PW-100L: Prototype engine for the YF-22; rated 30,000 lbf thrust class. YF119-PW-100N: Prototype engine for the YF-23; rated 30,000 lbf thrust class. F119-PW-100: Production engine for the F-22A with larger fan and increased bypass ratio (BPR) rated for 35,000 lbf thrust class. YF119-PW-611: Prototype engine for the X-35.
The Pratt & Whitney F135 is an afterburning turbofan developed for the Lockheed Martin F-35 Lightning II, a single-engine strike fighter.It has two variants; a Conventional Take-Off and Landing variant used in the F-35A and F-35C, and a two-cycle Short Take-Off Vertical Landing variant used in the F-35B that includes a forward lift fan.

The aircraft was equipped with a 2,240 horsepower engine, a top speed of 426 mph, and a maximum range of 520 miles. Additionally, it was armed with two 20mm MG 151 cannons in its wings and two ...
Model number Odd numbers for the United States Air Force and even numbers for the United States Navy. For example, the TF39-GE-1C is a Turbofan built by General Electric and was an Air Force model, which has powered the Lockheed C-5 Galaxy and the Pratt & Whitney TF30-P-414A is a turbofan built by Pratt & Whitney and was a Navy model, which has powered the Grumman F-14A Tomcat.
