The F-35 is not an original idea, though it is the first of its kind to be developed. Back in the 1960's, the Kennedy administration urged the development of a jet that could be used by both the Navy and Air Force. The product of the Kennedy administration's push, the F-111, was a multi-million dollar lemon. The Air Force took the F-111's concepts and designs and later produced the F-35.

The F-35 is commonly described as a "one-size-fits-all warplane, as its many capabilities allows it to complete just about any mission needed out of an aircraft (other than transportation and cargo).

The Pentagon set up a "contest" between the top two aircraft developers, Boeing and Lockheed Martin, to create the JSF to the needs asked for by each branch. Both companies succeeded in their designs, varying only slightly, but came down to the financial side of things. Lockheed Martin offered a slightly better pice for their version of the JSF.

Used by the F-117, B-2, F-22, and F-35, Digital Fly By Wire links the pilot to a computer program that compensates for lost stability due to design or, in the F-35's situation, hovering. using a very advanced gyroscope and pitch-and-roll sensors, the program controls different control surfaces (such as the rutters) on the exterior of the aircraft to stabilize it.

total overview of what STOVL is.

this shows the difference between the original STOVL design with the harrier and the new F-35B variant. This shows the difference Fly-by-wire makes.

The Joint Striker Fighter program, exhibited in the F-35 lightning, was built for the job of a multi-role, air-to-ground fighter with air-to-air abilities. The F-35 was built to fit the desires of all branches of the military including the United Kingdom Royal Air Force and Navy, making it as versatile as possible. To meet the needs of these different branches, Lockheed Martin developed four different versions of the JSF.
Jake Morain's comment, February 20, 2014 7:45 AM
Air Force Variant(A) - internal gun, infrared sensors, and laser designator. Navy(C) - larger wing and additional tail control enable low-speed approaches to aircraft carriers. USMC(B) - rotating rear exhaust for vertical takeoff/landing. UK - same as USMC

F-35 Joint Strike Fighter benefits from modern software testing, quality assurance

F-35 Joint Strike Fighter benefits from modern software testing, quality assurance | Aspect 1 - The F-35 Lightning II |
The Lockheed Martin F-35 Joint Strike Fighter (JSF) is a novel aircraft for a variety of reasons, not the least of which is its software. The fifth-generation fighter jet reportedly comprises more than 10 million lines of software code, segmented into blocks and largely written in C andnbsp;C++; yet, it also uses software code in the Ada computer programming language from the Lockheed Martin/Boeing F-22 Raptornbsp;military fighter aircraft.

The F-35 Lightning II, among the most complex military platforms to date, has suffered some production and deployment setbacks due the sheer volume of software code employed. Yet, aerospace and defense technology firms are working hard to remedy the situation.

The F-35 runs the Integrity DO-178B securely partitioned,nbsp;safety-critical, certified real-time operating system (RTOS) fromnbsp;Green Hills Softwarenbsp;in Santa Barbara, Calif. Datel engineers implemented the LDRA tool suite for software verification related to the F-35 engine, and developers at Parasoft Corp. in Monrovia, Calif., are working directly with Lockheed Martin engineers on static code analysis for JSF.

bEngine assurancesb
Engineers at Ultra Electronics Controls (formerly Datel) in West London, U.K., selected LDRA software verification tools for their work on the Pratt amp; Whitney F135, the engine of choice for the F-35 Lightning II fifth-generation tactical fighter developed by Lockheed Martin in conjunction with BAE Systems and Northrop Grumman.

Datel engineers had specific technical requirements related to their work on the Engine Ice Protection System (EIPS) for the Pratt amp; Whitney F135 Engine on the Lightning II Joint Strike Fighter project, and the Wing Ice Protection System (WIPS) for the Boeing 787 Dreamliner. They needed a software verification tool able to integrate with their target environment, which included the Texas Instruments TMS320F2812 and TMS320F2808 digital signal processors (DSPs).

Datel personnel made use of LDRAs complete structural coverage analysis solution at unit, integration, and system test levels. These tests were applied to source and object code, making use of the LDRA tool suites red-box mode.

It was important to Datel that it was able to develop their software to a known coding standard and, consequently, MISRA-C:1998 was selected to be applied to this code, a company representative describes. The LDRA tool suite simplifies the process by enforcing various standards using drop-down menus, which proved important for Datel.

Datel staff also needed an automated, intuitive unit testing tool which would save time, free up highly qualified staff, increase test efficiency, and improve motivation to test through a repeatable, less error-prone process. They found their solution in TBrun, LDRA's tool for the automated generation and management of unit tests. In the end, Datel reduced the time needed to confirm the verification results and increased the repeatability of its internal process.

bQA on JSFb
Lockheed Martin officials in the Maritime Systems amp; Sensors (MS2) business unit selected Parasofts Jtest, C++test, and Insure++ tools in 2004 to support quality testing for its software. (The MS2 unit became the Lockheed Martin Mission Systems and Training, or MST,nbsp;unit in 2012.)

quot;Our systems provide critical support when lives are on the line,quot; Martina DelRocini, softwarenbsp;subcontractnbsp;managementnbsp;at Lockheed Martin, explains. quot;Quality assurance throughout our processes ensures our systems meet their demanding requirements.quot;

Jtest and C++test automatically verify compliance to coding rules while generating and executing unit tests to ensure quality early in the software development lifecycle. Insure++ detects memory errors, such as corruption, leaks, and allocation errors in C/C++ code.

This relationship with Lockheed Martin demonstrates Parasofts ability to help large-scale software development organizations prevent software errors in what are some of the most complex systems being developed today,quot; adds Larry Johnsen, Parasoft director of military/aerospace solutions. Parasoft'snbsp;Software Development Compliance solutionnbsp;provides code analysis for compliance with the Joint Strike Fighter Air Vehicle C++ Coding standards.

"Our expeditionary operations are rapidly evolving, and the [F-35C]'s capabilities give us a flexibility to stage our aircraft not just from major bases and carriers, but also out of damaged airstrips and other austere operating sites." said Lt. Col. David Berke of the USMC.

Lockheed F-35 Lightning II - The F-35 Lightning II will usher in a new era of flight - that is - if all of the predictions heaped upon the aircraft come to pass..

Jake Morain's comment, February 20, 2014 9:01 PM
With the completion of the STOVL (short take off vertical landing) variant, Lockheed Martin will be the pioneers of STOVL supersonic fighter jets with the Marine's variant of the F-35. The STOVL will enable the jet to land on almost any surface, just like a helicopter, allowing it to assist troops closer to the front line.
Jake Morain's comment, April 7, 2014 9:48 AM
The US Military was looking for a multi-role fighter/fighter-bomber that could replace a number of different fighters and bombers. They The goal of the Joint Strike Fighter program was to incorporate new and old stealth technology and practices and advanced computer processing and systems.
