Iranian Su-25 Fighterjets Shot at U.S. Drone

BREAKING NEWS :

Thursday November 8, 2012 – Two Iranian Sukhoi Su-25s (Su-25K Frogfoot-A? or Su-25UBK Frogfoot-B?) would have fired at a U.S. drone last week on November 1, at 04.50 am (Eastern Time) as it was flying above international waters – 16 miles off the Kuwaiti coast, according to the Pentagon.

The General Atomics MQ-1 Predator unmanned aerial vehicle (UAV) was not above Iranian territory when it was intercepted by Frogfoots which engaged the drone. However, the Predator was not shot down, and returned to its base.

George E. Little, Press secretary of the U.S. DoD (Department of Defense) stated: “We have a wide range of options from diplomatic to military.”

Reminder: an American RQ-170 Sentinel UAV had been captured in Iran on December 13, 2011.

CHINESE J-31 STEALTH FIGHTER AIRCRAFT

The brand new 5th-generation fighterjet Shenyang J-31 – or F60, which would be nicknamed Gyrfalcon – took off on October 31, 2012. She thus performed a test flight – probably her maiden flight – on Wednesday.

This futuristic PLAAF (People’s Liberation Army Air Force) stealth multirole jetfighter looks like an F-35 Lightning II though the Gyrfalcon (or Falcon Eagle?) turns out to be a twin-engine a/c. She would be more maneuverable but smaller than the latest Chengdu J-20 Black Eagle stealth fighter. Her radar cross section (RCS) might be very small, and stealthier than recent 5th-generation fighter aircraft as the radome mounting looks as if it were – like the rest of the airframe – designed with reentrant shapes.

This fighter aircraft would not exceed Mach 2, and she features a DSI (Diverterless Supersonic Inlet) so that the airspeed can be reduced while entering the air intake, thus preventing the engine from breaking up.

Here are a few pictures, and videos:

ROLLING HALLOWEEN !

THE ROLLING STONES - GRRR!

© Walton Ford – The Rolling Stones

I guessed it could be an appropriate single for this blog today as you can hear Mick Jagger singing “DOOM and GLOOM”, the latest hit of THE ROLLING STONES who still ROCK!

It’s a short story well appropriate indeed since it talks about a doomed airplane as you can read the lyrics on the video here below:

HAPPY HALLOWEEN !

LANDING – HOW DIFFICULT IT CAN BE…

 

WarningThis voice communication does not comply with the International Civil Aviation Organization’s (ICAO) recommendations. However, you can click off, and listen without reading the script on this video in order to jot down this radio communication for listening training purpose:

These things happen.

  1. Bearing reported with a ninety-degree error, then corrected;
  2. Uncertainty of the downwind leg;
  3. Traffic not in sight;
  4. Uncertainty as to which airport is in sight;
  5. Requests are said again;
  6. Another airport in the vicinity with same runway configuration;
  7. Traffic off course;
  8. Within half a mile, no traffic in sight, and no radar tracking;
  9. Pilot cannot hear at times or does not reply;
  10. Confusion between ident and squawk;
  11. Pilot does not know how to use the transponder;
  12. Uncertainty of the type of aircraft, then corrected.

Landings may be difficult at times, indeed…

Mach-3 SR-71 Blackbird’s HOT COCKPIT

Blackbird onboard USS Intrepid – Photo © Xavier Cotton http://passiondesavions.blogspot.fr

As you may have heard, the mythical Lockheed SR-71 Blackbird was a strategic reconnaissance aircraft able to fly at more than Mach 3 – Mach 3.3 ie around 3,500 km/h; or 1,900 kts; and at a maximum flight level of… FL 850 or 26 kilometers high!

The Blackbird indeed had a unique flight envelope with a particular doghouse plot (since she could not exceed 3.5 G), and an exceptionnal coffin corner limited by her CIT – Compressor Inlet Temperature of 427°C maximum.

This aircraft was also unique for her engines were two J58 ramjets fuelled by JP-7 especially refined for extreme flying purpose. This special fuel could drip and leak abundantly as the airframe made up of titanium was retracted while taxiing, and became airtight only when it got its operating shape while flying very fast and very high because of the air density, and surrounding pressure plus the heating caused by the air friction at such speeds. In short, the whole structure considerably expanded when airborne.

The irony – I heard it on the grapevine, or read it somewhere on the web – that titanium which turned into dark blue while flying (SR-71s probably deserved those unofficial other nicknames “Bluebird”, or “Habu” viper) was “imported” from… USSR!

Pilots must have taken significant risks inherent in flying such an aircraft as mentioned in this previous post. These pilots used to fly over the USSR to take strategic reconnaissance photographs during the Cold war. They wore pressurized spacesuits so that their blood could not boil in case of decompression or ejection at such altitudes.

The Blackbird travelled faster than a rifle bullet, and the air friction could have melt aluminum-skinned aircraft. At Mach 3.2, fuel cycled behind the chine surface in order to cool the aircraft! The inner windshield temperature could reach 120°C even though a heavy-duty cooling system was on a full function. On landing, the outside temperature of the canopy could reach 300°C, and it must have been far beyond on the fuselage, and wing surfaces while flying at high speeds. The pilot could feel the heat behind his protective gloves!

Brand New AVIATION NEWSPAPER Born on Sound Barrier’s Day…

I guessed it might be a good idea to start a new aviation newspaper on the “Sound Barrier’s Day” if I may put it this way (October 14, 1947 ==> Chuck YEAGER, and maybe in a few minutes… October 14, 2012 ==> Felix BAUMGARTNER – Let us hope he will succeed in breaking both the sound barrier, and a new freefall record)
