FRENCH AIR FORCE BASES TO CLOSE DOWN:

The French Prime minister François Fillon has addressed an official statement this morning:

After the reform, “The French Army will have shed 20 Regiments/Batallions”, The Air Force will have shed 11 Air Bases,and the Navy will have shed “a Fleet Air Arm Base”.

The units or sites concerned are small, medium, and large ones – from tens of people up to 2,502 people as far as Metz AF Base is concerned.

  • As early as 2009, the French government plans the closing down of the AF Base 101 stationed at Toulouse.
  • In2010 Colmar-Meyenheim (Haut-Rhin) AF Base 132 should close down (1,276 people).
  • From 2011 -2012, Nîmes Garons Fleet Air Arm Base (1,332 people) will close down, as will the AF Base 112 stationed at Reims (1,545 people), and Taverny Air Base (Val-d’Oise, 986 people) as well. The AF Base 128 (Metz-Frescaty, Moselle, 2.502 people), AF Base 103 of Cambrai-Haynecourt (Nord, 1,364 people), AF Base 217 at Bretigny-sur-Orge (Essonne, 1,955 people). Overseas AF Bases: 365 Lamentin (650 people) in Martinique in the French West Indies, and overseas AF Bases 190 Papeete – Faa’a (Tahiti), in Polynesia (920 people), and AFB 181 Sainte-Clothilde, La Réunion. The radar Air Force Base 943 Nice Mont-Agel is to be shed too.

While 83 military sites will close down, it is deemed that around 60 sites will be operationally-meant reinforced. Evreux (Eure) Air Force Base 105 is expected to get a reinforcement up to 800 people.

The French government plans 54,000 jobs to be axed in the Armed Forces and Defense within a seven-year period. The current France strength is 320,000 (without the Gendarmerie). The French Air Force should reach down to 50,000 strength.

First RAF pilot to fly F-22 Raptor

(source: http://www.af.mil)

A former RAF Leeming F3 pilot has spoken for the first time since arriving in the United Kingdom at the controls of one of the United State’s 5th generation fighters – the F-22 Raptor.

Speaking after a 7 ½ flight which involved eleven refuelling transfers, Flt. Lt. Dan Robinson spoke of his fortune at being the first RAF pilot to fly the aircraft. CLICK HERE TO WATCH THE VIDEO

Why not fly NUCLEAR AIRCRAFT ?

I was reading a gripping blog in French called “Objets du ciel » (broken link) when I bumped into an amazing article written by Carl Conrad. I first thought that this post was unbelievable. I daresay that all the articles he writes are amazing. I am going to report hereafter what I have read about this topic – nuclear-powered aircraft – from different sources, but Carl Conrad’s article is the one that inspired me most.

As a major oil crisis is looming, airlines are cancelling some less financially viable air links of theirs. The future of aviation as we currently know it, seems to be in jeopardy. Nothing seems to be used as a substitute for any current kind of energy, not even electricity. What about nuclear-powered engines?

Nowadays, nobody would bear any nuclear-powered test flights. However those tests did occur within a USAF-carried-out weapons system (WS 125-A) nuclear-powered bomber aircraft programme. Those tests were performed with a 1,000-kilowatt-nuclear jet engine airborne on a Convair NB-36H. This aircraft named « The Crusader », took-off 47 times during the 50s. The engine was not used for propelling. It only worked at an altitude which was deemed sensible. Those tests allowed to assess the nuclear engine drive performance. Every flight would involve troops deployment in the area to prevent as soon as possible from any accident fallout spreading. The aircraft was modified in order to enhance the five crew member’s safety. The USAF considered the concept not realistic and gave the programme up in late 1956.

However, this technology might be coming back to fly some drones for long-lasting flights. People might be relunctant to see nuclear-powered drones taking-off and flying past over their heads. Who knows? Maybe some day.

Another project to mention: Project Orion should have become a 4,000-ton, long-range spacecraft powered by controlled nuclear pulses, or explosions. For this purpose, a small test vehicle was built. It was dubbed « Hot Rod », and was conventional-explosive-powered craft. Finally, Orion was cancelled in 1965 because it would not have been politically correct and because of technical challenges.

I have not found a piece of information about nuclear-powered craft after the year 2004. By the way, if someone knows further information about nuclear-powered aircraft, they will be welcome if they want to add some comments.

SPECIFICATIONS:
Span: 230 ft. 0 in.
Length: 162 ft. 1 in. (as B-36H, the NB-36H was slightly shorter)
Height: 46 ft. 8 in.
Weight: 357,500 lbs. (max. gross weight)
Armament: None
Engines: Six Pratt & Whitney R-4360-53 radials of 3,800 hp each (takeoff power) and four General Electric J47-GE-19 turbojets of 5,200 lbs. thrust each
Crew: Five ( pilot, copilot, flight engineer and two nuclear engineers)

PERFORMANCE:
Maximum speed: Approx. 420 mph at 47,000 ft.
Cruising speed: 235 mph
Service ceiling: Approx. 47,000 ft.

NASA OBLIQUE WING CONCEPT

NASA Dryden flight

A program conducted between 1979 and 1982 at the NASA Dryden Flight Research Center, Edwards, Calif., successfully demonstrated an aircraft wing that could be pivoted obliquely from zero to 60 degrees during flight. The unique wing was demonstrated on a small, subsonic jet-powered research aircraft called the AD-1 (Ames Dryden -1). The aircraft was flown 79 times during the research program, which evaluated the basic pivot-wing concept and gathered information on handling qualities and aerodynamics at various speeds and degrees of pivot.

The oblique wing concept originated with Robert T. Jones, an aeronautical

engineer at NASA’s Ames Research Center, Moffett Field, Calif.

Analytical and wind tunnel studies Jones initiated at Ames indicated that a transport-size oblique-wing aircraft, flying at speeds up to Mach 1.4 (1.4 times the speed of sound), would have substantially better aerodynamic performance than aircraft with more conventional wings. At high speeds, both subsonic and supersonic, the wing would be pivoted at up to 60 degrees to the aircraft’s fuselage for better high-speed performance. The studies showed these angles would decrease aerodynamic drag, permitting increased speed and longer range with the same fuel expenditure. At lower speeds, during takeoffs and landings, the wing would be perpendicular to the fuselage like a conventional wing to provide maximum lift and control qualities. As the aircraft gained speed, the wing would be pivoted to increase the oblique angle, thereby reducing the drag and decreasing fuel consumption. The wing could only be swept in one direction, with the right wingtip moving forward.

The AD-1 aircraft was delivered to Dryden in February 1979. The Ames Industrial Co., Bohemia, N.Y., constructed it, under a $240,000 fixed-price contract. NASA specified the overall vehicle design using a geometric configuration studied by the Boeing Commercial Airplane Company, Seattle, Wash. The Rutan Aircraft Factory, Mojave, Calif., provided the detailed design and load analysis for the intentionally low-speed, low-cost airplane. The low speed and cost of course limited the complexity of the vehicle and the scope of its technical objectives.

NASA AD-1 X-plane

Piloting the aircraft on its first flight Dec. 21, 1979, was NASA research pilot Thomas C. McMurtry, who was also the pilot on the final flight Aug. 7, 1982. Powered by two small turbojet engines, each producing 220 pounds of static thrust at sea level, the aircraft was limited for reasons of safety to a speed of about 170 mph. The AD-1 was 38.8 feet in length and had a wingspan of 32.3 feet unswept. It was constructed of plastic reinforced with fiberglass, in a sandwich with the skin separated by a rigid foam core. It had a gross weight of 2,145 pounds, and an empty weight of 1,450 pounds. A fixed tricycle landing gear, mounted close to the fuselage to lessen aerodynamic drag, gave the aircraft a very « squatty » appearance on the ground. It was only 6.75 feet high. The wing was pivoted by an electrically driven gear mechanism located inside the fuselage, just forward of the engines.
