The AL-41 is a designation for two different Russian military turbofan engine variants by NPO Lyulka-Saturn.The original AL-41F, development designation izdeliye 20, was a variable-bypass ratio turbofan engine, designed for supercruise flight for the MFI (Mnogofunktsionalni Frontovoy Istrebitel, "Multifunctional Frontline Fighter") program, which resulted in the Mikoyan Project 1.44.
The DF design was based on a 1958 built prototype, the Julong, which was essentially a Soviet TE3 and was built with Soviet technical assistance. The DF used a 10-cylinder opposed piston engine of type 10E207. This was a copy of the Soviet 2D100 design, itself a copy of the Fairbanks Morse 38D8 ¾.
The DF-ZF is thought to reach speeds between Mach 5 (3,836 mph (6,173 km/h; 1,715 m/s)) and Mach 10 (7,680 mph (12,360 km/h; 3,430 m/s)). [5] The glider could be used for nuclear weapons delivery but could also be used to perform precision-strike conventional missions (for example, next-generation anti-ship ballistic missiles), which could penetrate "the layered air defenses of a U.S. carrier ...
The China Railways DF11 is a semi-high-speed passenger diesel-electric locomotive.It was an important scientific and technological objective of China's Eighth Five-Year Plan, and was designed for 160 km/h (99 mph) runs on the Guangzhou-Shenzhen Railway.
The New Zealand DF class locomotive of 1979 is a class of 30 Co-Co diesel-electric locomotives built by General Motors Diesel of Canada between 1979 and 1981. [2] Between 1992 and 1997, all the locomotives were rebuilt as the DFT class , a turbocharged version of the DF.
