MACH-20 AEROSPACECRAFT

New-York to Los Angeles in 12 minutes… It would have been a record-breaker, had it worked:

The DARPA and USAF FALCON project might give anybody the thrill of speed as this « aerospacecraft » has been designed to reach Mach 20 i.e. around 20,000 km/h; 5.6 km/s; 10,800 knots; or 12,400 mph depending on the air temperature, and the altitude which might be above at least FL900!

Unfortunately, the project seems to encounter major difficulties as the last test which unfolded on August 11, 2011 failed again. The previous one – also on an HTV2 – had failed in April. Click on the right-hand side picture to get further information on the first test. The Blackswift (HTV-3X)  had been designed by ATK; Boeing; Lockheed Martin; and Skunk Works to provided a strategic strike anywhere in the world within an hour. It was cancelled due to a lack of funds (see the HTV-3 shown in the following video):

 


 

  • DARPA stands for Defense Advanced Research Projects Agency
  • FALCON stands for Force Application and Launch from CONtinental United States
  • FL stands for Flight Level (FL x 100ft = altitude)
  • HTV stands for Hypersonic Test Vehicle or Hypersonic Technology Vehicle
  • RCS means here in the videos: Reaction Control System (and not Radar Cross Section)

AD-150 HIGH-SPEED VTOL DRONE

Thanks to its HTAL (High Torque Aerial Lift) advanced tilt-duct propulsion system, the AD-150 Unmanned Aircraft System (UAS) has been designed to take off and land vertically (VTOL) as well as reach a speed of about 300 knots.

It is still being developed by American Dynamics Flight Systems. Its airframe is to be made up of carbon fiber and kevlar materials. It could be one of the most effective drones of its generation with its versatile payload configuration; GCS interfaces; and interoperable data links. Its Pratt and Whitney engines could be feed with Jet-A; JP-4; and JP-5 fuel.

RAFALE omnipresent at Paris Air Show 2011

RAFALE Le Bourget Airshow
RAFALE Le Bourget 2009 – Xavier Cotton http://www.passionpourlaviation.fr

No other fighter aircraft will be as omnipresent at the Paris Air Show as the Rafale as it has been shorlisted for India’s MMRCA (Medium Multi-Role Combat Aircraft) tender along with the Eurofighter. The IAF (Indian Air Force) is to order 126 multirole fighter aircraft for a deal of up to $10 billion. The French Dassault Rafale is still in competition with the Swedish SAAB JAS 39 Gripen, and the American F/A-18E/F Super Hornet in Brazil.

The Rafale also remains with the Gripen, and the Eurofighter in the Swiss NAC competition in order to replace the Swiss Air Force F-5s. The French Air Force has already demonstrated through the Rafale its combat readiness in Afghanistan, and over Libya. Its brand new reconnaissance pod Reco NG is now flying, and it managed to strike moving targets with its laser-guided AASM – Air-to-Ground Modular Weapon – beyond all expectations.

Its new Thales RBE2-AA AESA radar is still being developed. It has already been tested, and should be fully operational next year.

ToT (Transfer of Technology) has been pledged for the Rafale if the Indian government were to make its procurement decision.

FLYING from Paris to New-York in 1.5 hours at Mach 4 !

This is the brand new project being designed by EADS, and supported by Japan as well as the French DGAC (Direction Générale de l’Aviation Civile – FAA or CAA equivalent). The European consortium has just unveiled its ZEHST project as the Paris Air Show 2011 is opening. ZEHST stands for Zero Emission Hypersonic Transportation.

This aircraft would be both a commercial airplane, and a rocket. It could cruise at « flight level 1056 » i.e. 20 miles or 32 kilometers above the mean sea level… The ZEHST specifications feature a speed of Mach 4 but according to the video below, it might reach Mach 4.5 i.e. 5,500 km/h or 3,000 kts through the stratosphere. It would use two independent turbojets for taking off, then it would gain speed thanks to two cryogenic rocket engines, finally two ramjets would propell the aircraft to hypersonic speeds.

The ZEHST is supposed to pollute far less than the Concorde as it would have a main cruise stage in the stratospheric layers, and according to EADS, its carbon footprint should be very low. There could between 60 and 100 passengers on board who could join Tokyo from Paris in 2.5 hours instead of 11.5, and New-York in 1.5 hours instead of 8! The prototype is expected to fly by 2020, and the first passengers might enjoy stratospheric flights around 2050.
