You won’t feel safe in any aircraft losing its engine power. It would be crazy as well to take off without an engine.

What happens in a helicopter? Imagine, you’re stuck in a fuselage with highly rotating blades just over your head, diving to the ground. Nobody wants to jump out, it would be like putting yourself directly in a mixer.

Now, you understand that a parachute wouldn’t be so useful. What you don’t know is that helicopters use their rotors as braking devices, still more efficiently than a real parachute.

autorotation

The dynamic energy of the rotor is used to increase the pressure below the blades and to slow down the vertical movement of the helicopter.

As soon as you notice that you have to shut down your engine(s), you must dive dramatically and gain as much vertical speed as you can, in order to reach the necessary forward speed (check your pilot handbook).

When you’re close enough to the ground, you pull up the collective stick, increasing the angle of attack of the blades. Simultaneously, you pull the cyclic backwards to bring the nose up and decrease the horizontal speed.

With this maneuver, you transfer the energy of the spinning rotor to the airflow through the blades. The speed of the airflow is decreased, the pressure is increased and the atmosphere will carry the aircraft again, for a short time, just as long as you need to land safely.

An obvious remark: the more energy the rotor has, the more speed you will be able to lose. The lightest helicopters need to add weight at the tips of the blades, simply to get more energy in case of an autorotation.

You will like this video: a great display with an RC helicopter, even landing upside-down!

What is this?? I found this video today and got very intrigued. Is it real or is it a fake?

It’s an interesting concept.


But it’s a fake. The thanks to Call of Duty prove it, as well as  a couple of other hints displayed in this video: (and yes, the buzz’s spreading! it’s a marketing success for the next release of the game)

 

Now a few comments on the first video. Some details make it obvious that you don’t have a real prototype, but a (very good) computer simulation.

– a good point: you have some recoil when the machine gun is firing. You wouldn’t allow a bigger caliber though, or you may risk to see your copter suddenly pushed violently backwards.

– but the guy doesn’t seem to pilot anything with his tablet. His movements don’t match the copter’s reactions.

– such a light helicopter wouldn’t be able to carry more than one single type of ammunition: simple bullets or incendiary, you have to choose. Still, you don’t even see an ammunition box. Even better: the gun is actually only the barrel of a gun. You have no ammunition feed or even a chamber… just the barrel.

– it is claimed that each rotor has its single actuation system, but we don’t see any actuator on the structure below the rotors or cyclic control on the blades:

– why those fancy colors on the video transmitted to the tablet? The concept was good; it was not necessary to try to add after effects making it more Hollywood than real.

Aaaand last but not least, if you believed the previous demo, how can you really believe that you permanently carry an auto-destruction charge in your aircraft? This would be a huge loss of payload, a big risk for the guys carrying it on the field. If it’s not a kamikaze concept from the beginning, then it’s a “too much” option.

Watch the end of the video to see the huge explosion (what quantity of C4 do you need to carry for this kind of explosion??)

 

I hope you enjoyed the movie, the Call of Duty & FPS Russia guys made a fantastic movie!

 

As a bonus, check out this video.

It looks real, but the 206 pilot may be a crazy stupid risk taking guy as he flies so close to a so huge explosion (did he know what would happen?)

Communication is not an easy thing when you want to promote your brand new product. Helicopters do not escape the rule.

A funny example happened today with the new AAS-72X+ of Eurocopter North America. How can you sell an aircraft that was never really flown before?

The AAS-72X+ completes the AAS-72X, first proposal to the US Army.

Yesterday, Eurocopter NA unveiled its new aircraft (http://armedscout.com/news-press-rel-2009-2012/04-02-2012.asp). It corresponds to the upgrade of the civilian EC145 (http://www.blueskyrotor.com/performance/oneaircraft/Eurocopter/EC145-EC145-T2)

This upgrade may offer some performance and avionics improvements, but the only visible part is major: the well known fenestron has been implemented.

The problem is to illustrate the capability of the helicopter, even if it never flew in its military configuration before. What could you do? It’s simple, use Photoshop! (Or Gimp)

Before:

After:

The trick was easy: add clouds in the background, replace the tail boom and rotor with a brand new fenestron drawn with a high performing 3D software, and there you are!

However, the fuselage remained the same, from the pilot’s attitude to the aircraft’s registration number.

Well played! It’s always funny to notice those details. Also the fake picture is really beautiful, it looks like it was real! No doubt that many people took it for a real picture today.

But a simple question stays: why would you believe that an aircraft that was just unveiled, had already been flown by the US Army?
