Could RAFALE benefit from F-35 glitches?

 

JSF F-35 Lightning II

F-35 Lightning II

The British Harriers were to be replaced by the F-35C. Do you remember? You may have learnt from the recent news that the carrier variant of the Lockheed Martin Aeronautics Joint Strike Fighter – CV JSF (Carrier Vessel variant’s Joint Strike Fighter) – F-35C was unable to catch the wire onboard the aircraft carrier during the latest landing tests.

Strange as it may seem, the F-35C’s designers may have not forecast what would unfold during a test flight while landing on an aircraft carrier:

The arresting hook (tailhook) never engaged the arresting wire as the clearance between the tail hook and the main landing gear’s tyre tread is too short for such a speed. An F-35C Lightning II missing her carrier landing has been reported even though some U.S. officials would have dismissed such information which might result from simulated tests.

Added to that is a software bug which had grounded the CV JSF for 6 days a few month earlier for the fifth-generation fighter aircraft might have encountered wing-folding input while flying!

As a result, the British Ministry of Defence might find a Plan-B solution as these design flaws, and some others which date back to November 2011 are deemed unacceptable for such an expensive fighter aircraft – $139.5 million for the F-35C (CATOBAR – Catapult Assisted Take Off But Arrested Recovery), and $150 million for the F-35B (STOVL – Short Take-Off and Vertical Landing). The latter can land on carriers but she is more expensive, and the JSF program costs have already increased several times.

 

Moreover, the JSF would not be able to fire AMRAAM air-to-air missiles as reported in this video:

And there’s even more: according to a Pentagon study team report, 13 areas of concern that remained to be addressed in the F-35 would have been identified. For instance, the Helmet Mounted Display System (HMDS) would not work properly…

The British MoD is therefore considering the purchase of either F/A-18E Super Hornets or RAFALEs for the RAF. The French Dassault which has already lost the Swiss NAC tender due to replace the Swiss Air Force’s F-5s, would be proposing a new offer with 18 RAFALEs at a cost deemed lower than the 22 SAAB Gripens’ one according to the Swiss press.

The RAFALE is still in competition with the Eurofighter in the Indian MMRCA tender. the Indian officials are expected to make a decision this week. To be continued… ==> We have just learnt (on January 31, 2012) that the RAFALE has won the MMRCA tender… :-)

Machine Guns – How they work

 

 

TRANSCRIPT of this video from 00′:28″ – hereafter:

 

At its core, a machine gun is a gun. Its job is to shoot a bullet.

A bullet is a slug of metal – usually either steel or lead. The bullet is packaged in a metal casing, and the casing is filled with gunpowder that is going to explode and fire the bullet out of the gun. The bullet casing also contains a primer – a small charge that explodes when you hit it. When this small charge explodes, it lights the main charge of gunpowder.

Most machine guns are rifles with long-grooved barrels. The barrel gets the bullet heading in the right direction, and the grooves spin the bullet so that it flies straight. At one end into the barrel is a mechanism called the firing pin. When you pull the trigger, the firing pin hits the primer, and makes the bullet fire. The bullet comes screaming out of the barrel at roughly the speed of sound.

The machine-part of the machine gun is the bullet-powered engine. When the shell fires, the bullet goes one way, and the shell casing goes the other. It is a perfect example of equal and opposite reaction. The energy of that shell casing can be harnessed to drive a spring-operated bolt.

The bolt does three things. As the bullet fires and starts driving the bolt back, the bolt can extract the casing and eject it from the gun. Then, as the bolt starts moving forward again, it can ram a bullet into the barrel, and then hit the bullet with the firing pin. The newly exploding bullet starts a cycle all over again.

A typical machine gun can shoot anywhere from one hundred to six hundred rounds per minute depending on the size of the gun and the size of the bullet.

So, that’s how machine guns work.

South-Korea – Airliner almost shot down by the military!

NEWS ALERT – The South-Korean Marines would have fired 99 rounds from Gyodong island at an Asiana airliner flying over the border area.

Happily, the soldiers did not manage to shoot down the plane, a South-Korean Airbus A321 on which 119 passengers had departed from Chengdu Airport in China. Thanks to its flight altitude, the aircraft could not be reached. Measures shoud be taken so that the soldiers can recognize a North-Korean bomber from a civilian commercial aircraft.

Assessing expenses allocated to operations in Libya

As far as Odissey Dawn is concerned, the cost of missiles launched would nearly reach $ 300,000,000 according to the Pentagon.

  • Almost 200 Tomahawks – almost $ 1.5 million each
  • Operating a fighter jet – $ 10,000 an hour
  • Almost 500 one-ton warheads – $ 40,000 each
  • One downed F-15 – $ 60 million
  • A limited no-fly zone – $ 30 to 100 million a week
  • Arming the rebels – up to $ 100 billion a year!
  • Humanitarian aid – $ 25 million so far
  • Rebuilding Libya – not mentioned
