Flying an F-22 Raptor – Amazing Experience

The Lockheed Martin / Boeing F-22 Raptor 5th-generation fighter aircraft is a supermaneuverable, or rather a HiMAT – Highly Maneuverable Aircraft Technology – fighterjet which can shoot the enemy before they even see it thanks to its cutting-edge stealth technology:

SAAB’s RAPID 3D MAPPING for Military Aircraft

RAPID 3D MAPPING is a superior awareness system able to generate three dimensional maps. It processes pictures shot by digital and thermal sensors added to live georeferenced data onboard aircraft; drones; and helicopters.

It was chosen by the SDMA – Swedish Defence Materiel Administration – in order to provide 3D imagery to Gripen simulators last year.

The images can be compared several hours apart to establish whether threats can be considered in the latest analysis. As you can see in this video, the result looks quite accurate and useful for network centric warfare (NCW) purposes:

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)

Navy SEAL helicopter possibly stealth MH-60 Black Hawk

Some pictures of a US Navy SEAL helicopter that crash-landed during the assault on Osama Bin Laden’s compound in Pakistan show some shapes different from a more traditional MH-60 Black Hawk.

This wreckage – the size of a Black Hawk – consists of a rotor with a disk on top of it; special fairings; and a fairly different tail rotor – with five, perhaps six blades.

However, thanks to David Cenciotti’s blog, and thanks to AeroManouch who passed this piece of information on, we can see that the tail rotor would rather have five blades, and it visibly is not an RAH-66 Comanche.

According to Bill Sweetman, a defense technology and aerospace pundit from Aviation Week, this chopper might be a Black Hawk upgraded into a stealth helicopter version:
