The Above Pic shows the HC2A Chinook Helicopter in a steep Angle with its personnel standing near the Door.
Whats going on & is there a deliberate attempt at trying something.

Damm, I didn't know they could do that.
Closest thing I have seen is photos of some USCG ship tow experiments, and hovercraft tows on the north slope of Alaska. But those helo's where tied to something really really big.
OBAMA-WORST PRESIDENT EVER....Even SKOORB would be better.

This photo was featured in a previous thread and it was pretty incredible then as well as now.
One of the Chinook pilots told me that the D-model CH-47 was the fastest helicopter in our inventory if one was willing to put it on its nose while in forward flight....I never really believed him until now.
I bet the crew chief in the window is going over his mental checklist to make sure that he did not forget anything during preflight maintenance.....that and praying to God that the pilot is as good as he thinks he is.
It would be a hell of a ride in the door like that.

Lift is not dependent upon angle as the rotory wings are creating lift by being propelled in their arcs.
Do you understand how lift works? Not being smart assed but I think if you dont it bears discussion and would make it clearer.

Sure do
But look at the pic,consider the weight of the Helicopter & imagine its weight & the height from the surface.

MEL, I truly was not trying to be an ass there when I asked the question, and reading my post my curtness could be interpreted as rudeness. Not intended, so please accept apologies if you felt a slight.
THe forward tilt assists in the initial acceleration of the aircraft when transitioning from the hover. The drag is not so much of a factor when accelerating from hover, and as the aircraft reaches cruising speed it will be flown at a more level attitude.
One engine shutdown does not have a catastrophic impact as the engines are both connected to the rotor drive shaft. It does present a problem when one engine is being used to lift a fully loaded aircraft at higher altitudes.

DL021......No Apoligies needed.Sometimes words sound different. [Chk my Signature]
I agree & Understand unless there is a sudden Thrust drop nothing serious could happen,But the question arose from the 2nd pic near the water surface,similiar to the question raised on a DC10 #2 Engine mounted on the Vertical Stablizer,when we look and say,can it hold the Engine [Although we know it can]
Cheers

We are talking about the picture in reply #2 correct? And we all see that massive bit of drag at the far end of the cable right?

Sorry, I was focussed on the photo in the originating post.
Yes, obviously that one would present some issues that the additional torque would be of extreme help.

Humble opinion coming up...
I reckon that this helo is in a (more or less) max rate dive.
Reasoning:
1. The rotor blades seem to be in a forward flight configuration; i.e., the rotorblade at the pointy end of the aircraft is more bent upwards than usual, while the other blades are rotating in more or less their normal configuration. If it was in level flight, one would expect all three blades to be almost maxed out (or, at least, the blades at the rear would be bent further 'upwards'), as if it were performing a vertical take-off.
2. The crew chief/loadmaster (visible in the door), while holding on, appears to be standing more or less straight. If the aircraft was in forward flight, one would expect him to have his hips hanging down slightly.
3. Helicopters will maintain constant altitude up to incredible angles. However, I reckon that this one is too far over to maintain level flight.
Bearing in mind the aircraft's mission, it would not surprise me in the least if this was practicing the helo equivalent of the Sarajevo landing (fall out of the sky, under power, and plonk it on the ground), somewhere near Odiham.
Like I said, this is only a guess (haven't yet worked with the Shìthook) and feel free to disagree.

Having worked on and flown in Chinooks for a few years, I can tell you that the aircraft is in a dive and not in a normal flight configuration. For the "D" model, even at max speed with the nose down, the aircraft's attitude is NOWHERE near as steep as that. Not sure why they're performing such a maneuver, but it has to be something extreme. While in the US army, we never took our birds to maneuvers of that extreme. If I was in that aircraft, the dive wouldn't scare me, but having to pull out of it would. The stress on the rotor system must have been incredible!

I can't give you exact dates, but they were operated from the early 70's to the early 90's. They were parked during the defense cuts of the early 90's. They parked them at the Mountainview storage base and it took a couple of years to move them.
The two main operating bases were CFB Ottawa (Uplands) and CFB Edmonton (Namao). They may have made it over to Europe on exercise, but if that happened it was very rare.
I actually got 3 rides in the ones based in Ottawa. Great machines and you could hear them coming for miles. They would make the whole house shake!

hey guys,
What you are seeing is a snap shot in time. There is no way the Chinook or any aircraft can maintain that attitude. What you are seeing is a "stunt" that RAF pilots do in thier airshow demos. I have a video of one doing that. What you are seeing is what a pilot does after a bump. The chinook is a very powerful airframe that can lift it's own weight. When it isn't loaded it is a quite capable aircraft... here is the video.

Cool video of the Chinook LongBowPilot!
Especially the roll on landing and subsequent reverse take off at 2:40minutes and the neg G pushover to steep nose down like the original picture at 4:20minutes.
