Do you see anything wrong with this PIC?

I mean landing gears are retracted and definitely not on display pole. So why both the doors are open?

1) Is it Russian way of getting fresh air? ( I would buy this if we confirm Heater/AC was broken  )
2) Sight seeing flight?
3) Cargo ramp agent was too lazy ?
4) Some kind of test flight?

Seeing as the aircraft is at the Antonov airport, I'd venture to say that it was some kind of test.

It's a test flight for their new contract with Santa Claus. He figured that he needed a backup in case his sleigh got damaged and Antonov provided a suitable cargo aircraft with airdrop capabilities - not a year too soon, either!

I would imagine they are testing some sort of procedure, as I cant even imagine the hydraulic pressure required to hold the doors open at any flying speed.

I wonder what procedure it would be though, as there must be some mechanism built for this. There also appears to be a step extended in place on both sides, when the door is open.

The engine cowlings have been swapped out very recently, those doors can give a pretty good view of them in flight...

Also re the step: are those forward doors useable as jump doors?

The only test I can google for Open-Door flight test is, test performed by NASA for SOFIA

Although I came across many depressurization handling training documents and video.

My thought was jump doors especially with the jump platform extended.. but right into the props??/

It's a military aircraft and is no doubt capable of dropping paratroopers. Usually you'd drop them out the back where its safer but maybe its alternate jump point.

The US transports since the C-130 have all used side drop doors, just aft of the wing.

Looking at photos of the aircraft from head on and on the ground - anyone exiting the door would be well clear of the props or even the immediate prop wash.

The props are about a 2/3 of a prop diameter from the fuselage and they are much higher than the bottom of the door.

How about a parachute? Aren't those designed to open as soon as the trooper is out the door?

Yes. A la Il-76



The purpose is to shield the troops while they jump. The C-130's have a something similar on the rear side doors.

And on the C-17 we have air deflector panels that extend into the airflow just forward of the troop doors for paradrop operations.

See the photo

Though the static line will start to pull the pack releases in just a few feet, the trooper will be well clear of the aircraft before the chute deploys fully.

Why don't they just scrap it or put it in a museum?

I've always wondered what a joint venture with EADS to bring it to requirements would have given...
It would have been a chaotic collaboration, but I'm guessing the resulting aircraft could have been a very interesting product indeed, and certainly cheaper than the A400.



Looks like I picked the wrong week to quit posting...

Actually, I believe all US transports capable of paratrooper drops have been out doors from behind the wing.

C-46, C-47, C-123, C-130, C-141, C-17

The C-123 was the first cargo plane that featured the rear cargo ramp. It required that the side doors be removed completely prior to flight for paratrooper dropping. There is an escape hatch in the floor just behind the cockpit on the main floor for use by people from the front of the plane in ditching because if you jump out the front side door, your going right into the prop.

There are orders for 65 of them: 5 for Volga Dnepr, 60 for RuAF. This prototype just started flying again in September after a massive upgrade program (avionics to reduce crew to 4, propellers for noise: see the new engine nacelles int he photo)

The AN-70 is another case of an aircraft appearing at the wrong time. It first flew right as the Soviet Union collapsed and the design customer - the Soviet Air Force - suddenly collapsed.

Which also put hundreds of AN-12 aircraft on the market, cheap, very, very cheap.

Given the birthing problems of the AM400, going back to make the AN-70 a potential competitor is probably a good business decision. Only time will tell.

But there are a lot of old AN-12 transports what need to be replaced by something.

Actually in the 1990s the Germans were interested in a joint venture with Antonov to produce a NATO compliant version of the AN-70, but the French government insisted on some old contract for what would now be the A400M and insisted that Germany would have to pay a huge fine if they would leave the project.

Good video. Explain it all.

Just curious- those door hinges must be strong and there must be some drag due to distortion of aerodynamic shape of plane. Wouldn't it make sense to have that door opens inside ? Like what SOFIA does.

[Edited 2012-12-25 15:12:11]

25 rfields5421 : The purpose of the door opening out is to provide realtively low airflow for the exit point. Otherwise the troops would have to fight their way out t
