Simulator shows viability of Joint
Strike Fighter
Collaborative work between The MathWorks and Lockheed Martin Aeronautics has led to the successful completion of the first simulated test flight of the F-35 Joint Strike Fighter.
Collaborative work between The MathWorks and Lockheed Martin Aeronautics has led to the successful completion of the first simulated test flight of the F-35 Joint Strike Fighter (JSF) using Simulink generated code Lockheed Martin's Chief Test Pilot, Jon Beesley, conducted an unrestricted evaluation flight in the F-35 real-time simulator lasting over 2h, performing a wide range of manoeuvres

Kit enables visualisation of DSP applications
A new DSP developers kit kit enables systems and software engineers to develop and verify DSP algorithms in one integrated environment, and therefore produce designs more efficiently.
Toolbox marries acquisition hardware and software
Users of Keithley Instruments' data acquisition boards can now communicate with their devices directly from Matlab via an interface provided with the Matlab Data Acquisition Toolbox.
He exercised the sophisticated flight control laws designed and generated by Lockheed Martin's JSF Flight Control Application Software team using Matlab, Simulink, Stateflow and Real-Time Workshop Embedded Coder from The MathWorks.
"Jon was given freedom to fly the aircraft through manoeuvres such as landing, formation, in-flight refuelling, and basic stability and control tests.
The control law software performed flawlessly throughout these tests, a notable outcome for simulated flights using a new toolset.

Software spreads to Mac platform
Matlab will be available on Mac OS X, Apple's advanced Unix-based operating system, with the next release of The MathWorks product line.
Performance results were very good and we identified several minor items for refinement", said Greg Walker, JSF Flight Control Application Software IPT lead, Lockheed Martin.
"Using The MathWorks tools, we were able to develop and test the control laws, automatically generate code, and, as a result, complete this milestone on our way to first flight".
The F-35 is considered the single most important new military aircraft to be produced over the next 30 years.
The programme will deploy 2593 aircraft for the US Air Force, US Navy, US Marine Corps, the Royal Air Force and the Royal Navy.
The F-35 family includes a conventional takeoff and landing (CTOL) variant, an aircraft carrier version (CV), and a short-takeoff/vertical-landing (STOVL) variant, which provide challenging requirements for the flight-control system.
Using a model-based design approach with Simulink and Stateflow, the flight-control engineers have developed the control techniques and generated the software to address those challenging requirements while reducing software development costs.
Additionally, F-35 engineers will use Matlab to rapidly perform flying-qualities and stability analysis, and to analyse the vast amounts of test data generated during the F-35 flight test programme.
"We have worked closely with Lockheed Martin for several years to enable them to create advanced control design systems technology for the JSF project", said Paul Barnard, Control Design Automation Marketing Director, The MathWorks.
"Together, we drove enhancements so their engineers can work with significantly larger models and dramatically reduce their downtime when modelling, simulating, and implementing their designs.
These enhancements are now incorporated in Simulink 5.1, the latest release".
