2005-01-3180
Real-time simulation is an integral part of the Vehicle Systems and Mission Systems design and risk reduction processes for the three variants of the Joint Strike Fighter (JSF), or F-35, aircraft-Conventional Take-Off and Landing (CTOL), Short Take-Off and Vertical Landing (STOVL), and Carrier Variant (CV). ...The JSF Program is relying on increased use of modeling and simulation to reduce verification cost and schedule. The F-35 Lockheed Martin/Northrop Grumman/BAE SYSTEMS team utilizes the unique motion capabilities of the NASA Ames Vertical Motion Simulator (VMS) for control law and pilot-vehicle interface design maturation and evaluation. ...This paper discusses real-time simulation usage for F-35 control law and pilot-vehicle interface design. Results from the February/March 2004 NASA Ames VMS simulation, as well as preliminary results from LM Aero's-Fort Worth, TX motion-based simulator, are summarized.

2009-01-3280
In order to meet the F-35 Joint Strike Fighter's strict radar cross-section and weight requirements, stealth coatings must be applied to extremely precise thickness tolerances. ...The iterative process of optimizing spray parameters and robot programs for coating thickness control on challenging F-35 geometry is also presented. Finally, results from the first coating of a production aircraft at RAFS are compared with previous hand-spray results.

U.S. DoD orders 255 Lockheed Martin F-35 military combat aircraft in $22.7B deal

2018-11-16
Department of Defense (DoD) to deliver 255 of its F-35 fifth-generation military combat aircraft. The Naval Air Systems Command, Patuxent River, Maryland, issued the contract modification to a previously awarded firm-fixed-price advanced acquisition contract (N00019-17-C-0001) for Lockheed Martin’s F-35 Lightning II family of single-seat, single-engine, all-weather stealth multirole fighters designed to perform ground-attack and air-superiority missions. ...The Naval Air Systems Command, Patuxent River, Maryland, issued the contract modification to a previously awarded firm-fixed-price advanced acquisition contract (N00019-17-C-0001) for Lockheed Martin’s F-35 Lightning II family of single-seat, single-engine, all-weather stealth multirole fighters designed to perform ground-attack and air-superiority missions.

It then explores the I/O Technology Suitability Study criteria used to originally select IEEE-1394b (Beta) as the Vehicle System Data Bus for the F-35 Joint Strike Fighter and update each criterion with new information based on more than a decade of experience and use in not only the F-35 but several other programs. ...It then explores the I/O Technology Suitability Study criteria used to originally select IEEE-1394b (Beta) as the Vehicle System Data Bus for the F-35 Joint Strike Fighter and update each criterion with new information based on more than a decade of experience and use in not only the F-35 but several other programs. Based on the suitability study criteria, the reader gains insight into how and why programs like the F-35, which implements dozens of AS5643/IEEE-1394 devices per plane, utilize AS5643/IEEE-1394 for its vehicle system network. ...Based on the suitability study criteria, the reader gains insight into how and why programs like the F-35, which implements dozens of AS5643/IEEE-1394 devices per plane, utilize AS5643/IEEE-1394 for its vehicle system network.

2005-01-3267
Lockheed Martin Aeronautics is currently in the process of modifying a 737-300 aircraft from the standard airline configuration to an avionics test bed aircraft for use in developing the Joint Strike Fighter (JSF) F-35 avionics suite. As simple of a concept as this implies, it is actually a complex design evolution as there are no recognized “standards” for test bed aircraft.
