Title: Gunship helicopters
Post by: ysi_maniac on September 04, 2017, 03:36:45 PM: Is it possible to aim a fixed gun with a helicopter?
Is it possible to fire an antitank gun (I mean 50mm to 105mm) from a helicopter?

No more difficult than it is from a conventional aeroplane. Just align it alone the axis of the aircraft and point the whole helicopter at the target.

A bit harder but if the helicopter is strengthened to withstand the recoil, I don't see why not. Make the gun recoilless and it would have no problems with the recoil.

There have been numerous plans for making recoilless weapons semi-automatic in reloading.

Part of the US Army's early experimentation with armed helicopters; Cobra! The Attack Helicopter: Fifty years of Sharks Teeth and Fangs has a close-up of this B-29 remote turret installation in the chapter on early armed helicopter experiments (upper photo, page 8 of the hardback, if you're picky). The USMC was in a similar effort and there is also a picture of a Sikorsky H-34 with a very large gun pod as well as one with 16 tube-launched rockets on each side.

"Another attempt at helicopter mounted artillery. This US Army Weapons Command concept drawing shows a 105mm howitzer mounted on a CH-47 Chinook helicopter."

Post by: elmayerle on June 29, 2019, 08:24:11 AM: I could see the 105mm howitzer mounted on the rear ramp of a Ch-47 rather than a side door/ramp.

I do like the CH-47 proposal though. HAs the advantage of being able to carry ammunition plus gun crew as well.

Post by: GTX_Admin on June 30, 2019, 06:48:56 AM: A proposal from 1972 - a CH-47C helicopter with two 105mm XM-204 howitzers:

(https://miro.medium.com/max/1400/1*0FFL3lVjKgEsDBGFyZKWyA.jpeg)

The XM204 used a ‘soft recoil’ system, where just before firing, the gun barrel assembly would be pushed forward by a pneumatic system pressurized with nitrogen gas. As the gun barrel assembly moved forward the gun fired, and recoil energy would have to overcome the forward momentum of the gun barrel and breech. This would disperse most of the recoil energy, allowing the XM204 to dispense with the usual trail associated with towed howitzers.
