Successful Trials New Joint Strike Fighter http The new Short Take Off and Vertical Landing (STOVL) F35 Joint Strike Fighter is another step closer following successful trials of :// the aircraft’s advanced flight control software which will enable ww pilots to land onboard ship in all weathers, day and night with w.fl ‘centimetric accuracy’. The trials, carried out onboard HMS Illustrious using a veteran two seat eeta Harrier airframe, the Vectored-thrust Aircraft Advanced Flight Control irar (VAAC) Harrier, put the new system to the test. The Harrier has been heavily modified with a conventional control arrangement in the front moa cockpit and the rear being connected instead into an experimental fly- .org/ by-wire system using left and right hand interceptors to manoeuvre the aircraft and simulate the way the new Joint Strike Fighter will fly and Con respond to different inputs. 66 running landings and recoveries were tent/ achieved in varying sea states up to and including sea state 6, with outstanding results. incepts/inceptors site The test aircraft, XW175 is the oldest flying two seat Harrier in the s/ world.

Lockheed Martin Continues Joint Strike Fighter Tests at SimLabs January 2006 http://www.simlabs.arc.nasa.gov/newsletter/archive/newsletter_01_06.html “Lockheed Martin continued evaluations of the F-35 Joint Strike Fighter (JSF) aircraft in SimLabs’ Vertical Motion Simulator (VMS) http://www.simlabs.arc.nasa.gov/vms/vms.html [amazing setup] by recently compl- eting four weeks of simulation experiments. The unique motion and acceleration capabilities of the VMS are ideally suited to evaluate the handling qualities of several variants of the F-35. The JSF is a next-generation supersonic combat aircraft designed to reduce costs by utilizing a common design with variants to meet a wide range of needs serving the U.S. Army, U.S. Air Force, U.S. Marines, as well as several international par- tners. Two variants were recently evaluated in the VMS: The Short Take-off Vertical Landing (STOVL) config- uration and the Conventional Take-off and Landing / Carrier Variant (CTOL/CV). The STOVL configuration was the primary variant studied. This configuration required high fidelity motion cues to evaluate tasks that included bolter and ski ramp take-off.A bolter is an aborted carrier touchdown that requires full thrust to take-off after the abort. The ski ramp take-off is a short deck take-off at full thrust [in STOVL MODE] using a ramp at the end of the deck. Both maneuvers require high vertical acceleration cues to simulate accurately. A secondary variant was the CTOL/CV. For this variant, most of the effort was aimed at first flight readi- ness and tasks such as formation flying or offset approaches requiring a high level of motion fidelity to fer- ret out any issues with the control system. As part of this study, representatives from the United Kingdom Ministry of Defense evaluated a Shipboard Rolling Vertical Landing (SRVL) procedure as one more determinant in their choice between the variants men- tioned above. The procedure is tied to a new aircraft carrier design under consideration and will have signific- ant cost ramifications on the carrier design. For the SRVL procedure, touchdown dispersion and ramp clear- ance under various shipboard and environmental conditions were evaluated. Several aircraft controls handling issues were identified that need further investigation giving designers the opportunity to improve the system while the vehicle is still under development.” CHARLESDEGAULLE CdeG IFMQT+4'QSPHSBNNF The UK’s QinetiQ and the MOD Joint Test and Evaluation Group, which http://navyleague.org.au/wp-content/uploads/ comprise the UK Aircraft Test and 2012/06/The-Navy-Vol_69_No_4-Oct-2007.pdf Evaluation Centre, are currently undertaking a series of landing trials of a short take-off vertical landing (STOVL) aircraft on to the French Navy’s CHARLES DE GAULLE carrier, using QinetiQ’s Vectored-thrust Aircraft Advanced Control (VAAC) experimental Harrier.
