PATENTED LIFT FAN SYSTEM Lockheed Martin patented JSF shaft-driven lift fan system produces 60 per cent more vertical lift in the STOVL mode with a cooler ground footprint than direct lift systems
The design of the 'America' class is based on the design of the US Navy's 'Wasp' class AAS (of which it operates eight; also procured to replace the Tarawa' class), but missing a well deck to enable more storage space for aircraft such as the United States Marine Corps' Lockheed Martin F-35B Lightning-II STOVL Multi-Role Combat Aircraft, its Bell-Boeing MV-22B Osprey tilt-rotors, Sikorsky CH-53K King Stallion heavylift helicopter and Bell UH-1Y Venom medium-lift utility helicopters.
But, he notes that the British usually conceived and fielded new concepts: the steam catapult, STOVL Sea Harrier, and ski-jump deck are several examples.
Harrier proponents prevailed and marines believe the past two decades proved there is a place on the battlefield for STOVL tactical aviation.
The first STOVL aircraft has been at Naval Air Station Patuxent River Maryland since November 15, 2009, completing a series of test flight activities on ground and in air, including static testing and in air conversion flight tests leading up to the first vertical landing.
The F136 GE/Rolls-Royce team's effort does not include design, development, test, and delivery of STOVL Lift System components and exhaust systems, which are developed and provided under the F135 Pratt and Whitney SDD contract.
The additional pair are the hot gas laboratory, mainly used to examine ground erosion caused by short take off and vertical landing (STOVL) planes on landing, and the advanced gas facility which also tests aspects of STOVL, such as hot gas ingestion, as well as planes' reaction control systems.
Although the Marines procured a V/STOL attack aircraft, it was used from the beginning as a short takeoff and vertical landing (STOVL) machine and developed operating concepts and tactics, techniques, and procedures to employ it almost exclusively in the STOVL realm.
These include updating the RAF's ground attack Tornadoes, with our partner BAE Systems, with new precision weapons, and proving our technology for automatic landing of STOVL (Short Take Off and Vertical Landing) aircraft at sea, for ultimate use on the Joint Strike Fighter.
I do believe that the British and USMC STOVL (short takeoff and vertical landing) version of the JSF could be of great interest to the Japanese for use on their new 16DDH carrier-like helo destroyer, but the Japanese Defense Agency has not taken that position as far as I can tell.
Because of the design similarities among the three F-35 variants, many of the STOVL-version refinements will translate to the conventional and carrier versions, which already met their performance requirements even before the STOVL improvements were instituted.
R)isk reduction on the STOVL becomes one of the paramount things to do .
