Aircraft

Is anyone working on solving loss of tail rotor function from RPG's as seen in the movie "Black Hawk Down"? I've wondered this for many years, whether or not it's possible to design a system whereby tail rotor loss of function could be minimized by some kind of emergency jet propulsion in the tail section to produce the necessary thrust for safe control of the helicopter or by directing engine exhaust in a sidewards manner much like an engine reverse thruster to minimize or eliminate torque thrust. I'm also wondering why the military does not employ the NOTAR system in combat zone helicopters to mitigate being brought down by RPG's. Any helicopter engineers or pilots wish to comment?

could pivot in any axis, --via pilot controlled hydralics, say 90deg in any direction --wouldnt that give you ultra-maneoverability? ( i mean mass produced planes, not like a one-off experimental)

For awhile, you saw lots of DC9's., 727's. BAC 111,'s, L1011-s. and Dc10's, The 1011's and DC10';s had one engine in the rear, the others had all in the rear.
Now, you see rear engine designs in regional jets and B717's.
Everything else, Boeings and Airbusses, have their engines foreward, under the wings.
Why did the rear engine mount fall into disuse??

I know there is a weight issue in aircraft but lapbelts are dangerous and can cause serious spinal injuries.

Last week, I was on a flight that depressurised (fun and games). We were told was there was a problem with the air conditioner, next thing you know we’ve got oxygen masks. So, 3 questions:

1) What does the air conditioner breaking have to do with cabin pressure?

2) What are the risks involved with decompression? (Slow depressurisation, not explosive.)

3) What are the actual statistics about planes’ depressurising? (How often does it happen?)

After I touchdown, I use full rudder either left or right [depending on the wind direction] and centre it when the nose starts to become aligned with the centreline on the runway. However, in most cases, the nose happens to kick back in the other direction after I centre the rudder; this causes my aircraft's nose wheel to touch down misaligned and the plane loses its line with the runway. I have to correct the aircraft again; however, I know that this is not the proper [nor the recommended] way to align the plane with the runway after touchdown~

Why do a lot of military planes such as the c-17 have their wings above the fuselage while most of the commercial aircraft have the wings underneith?

Also if someone would know how many liters the take-off (first 1,5 km/0,93miles) consumes.
Thanks.

For example, the 737 has engine cowlings that are flattened on the bottom for more ground clearance, I presume. It seems much less common now to see planes with engines in the rear, too, like the MD-80.

It seems like it would be OK to have the engines above the wings. This would allow the landing gears to be shorter (maybe?) thus reducing the likelihood of landing gear shimmy. It would also reduce the likelihood of foreign object damage (FOD) in the engines.

Perhaps the engines are so often under the wings in order to simplify maintenance, but it seems like the landing gear shimmy and FOD problems are more important ones to solve.
