ATS Project: Attack Chopper

Hooz up for designing Attack Choppers?, We designed the ATS one which was a fighter so i came up with the idea of designing attack choppers.

I still have some drawing done by me from ages ago, i may scan them up.

Anyone else out there have some designs?

Ya me, I made a model of one, will post and scrounge when i get free time tommorow.

I have a few ideas, it will take me couple of days to put it into 3d...

Damn i wish i could draw so i wouldn't have to do everything in 3d to make it possible to people to understand my ideas

I can't draw on the computer and I was less than impressed with the way my scanned pencil drawing on another thread like this turned out so I will pass.

However this thread does remind of the time at school I designed an ASW helo in tech drawing (about 1981) which looked almost identical to the EH101, which wasn't even invented at the time! I also did a swept wing Citation about four years before Cessna got round to it.

Just some ideas for all of you, Still trying to find my old drawings

Heres one i did recently, I called it ah70.
Also uses vectored thrust instead of tail rotor.

Here are some short renders with the textured version:

ya i know they are crappy, but its a work in progess!

Only arms it has so far is a mini gun on the front:


heres the mini gun, its standard...

Cool idea, I'll participate, just gotta go looking for some designs,
or in the case I can't find one, I may have to design one.
And I know, my designs are sorta suckily drawn, but they look cool
in my head, just not so much on paper when I draw them.

Preliminary sketch:


* Shrouded rotor reduces drag, protects in case of impact (trees etc), increases cruising speed

* Mast mounted combined sighting and missile turret with 360degrees transverse (limited in the case of missiles due to FOD issues on launch)

* Possibly TVC instead of tail rotor (also considering pusher propeller or jets)

I haven't got any pictures, but I can give you a pretty good visual.

Take a RAH-66 Comanche.

Strip off the rotor assembly.

Place two ducted fans or really thin jets on the side (capable of hefting up the mass of it). These can pivot in the axis that they are connected to the body on a la Osprey.

Remove the rear stablizer wing and turn the rear prop on its side (so it pulls the tail up and down, instead of side to side).

Voila. Here you have a very maneuverable aircraft that is capable of moving from VTOL to horizontal flight, has some good speed capabilities, and can give modern helicopters a smackdown in terms of agility. If this thing had quick-response jets on its sides I would love to see this. A small fleet of these and SEAD operations would go together like Laurel and Hardy.

Jesus planeman how do you do that so fast ?

Preliminary sketch......
and out comes the comanches rival ...WTF ?>
Took me a couple days to finish with just the drawings !

Its always dificult to make a cool looking heli, they require so much power that a ducted fan usually isnt efficient, I dont know if we are making for relaity or something cool, but in any case, ducted fans are mucho inefficeintio

True in some regards. I'm half serious, hald playing. Shrouded fans have cropted up many times - the main advantages:

* Massive reduction in "tip drag" makes it more efficient in forward flight - plus the shroud can be formed into a wing.

* Increased robustness - less concern of the rotor hitting trees/buildings



BUT, it adds hell of a lot of weight which detracts from vertical take-off efficiency - it'd have a smaller weapons load than the equivilent conventional helicopter and we less well suited to hovering.

Despite much talk, I don't think anyone has actually got around to flying one (an otherwise conventional helicopter but with a shrouded fan) so that is a pretty good indication of the percieved advantages.

Ok, I have some questions I need to ask before I can finish my design.


1. Does it have to be strictly a helicopter, or can it be a helicopter,
and have the abilitie to fly like a tradional jet plaen as well?

2. Can it use technologies that don't quite exist, but will in the
next two decades?

3. What's the size and crew limit for for it?

HEy anything goes dude, bring your most whacked out bird to the table. I am guessing we are going to get specific later on.

Planeman: I think ducts would be cool becuase they would increase the foward speed of a helicopter because the leading tip would not cause the roll effect in high speed flight...BUT !!! Ducts are ducts, and it would mean its no longer a heli by definition.
I dont know if im right or wrong just throwing my thoughts out.

Anyone have any duel bladed choppers..one on top of another, this would at least get the speed up to 250 mph. Maybe we can make a heli that uses the old x wing thing, where the blade stops in mid air and becomes a static lifting surface ?

If you want your Chopper to reach 250mph, Design it like the AH-56 Cheyenne

So, when exactly is the due date for designs?

I'm nearly finished with mine, already drew it, scanned it,
now I'm just doing some editing to get rid of some
imperfections that were vastly magnified with the scanning.

Anyways, since I have'nt finished the editing to post it,
I'll describe it, just so no one thinks I'm being lazy, and
have'nt done it yet.


The fuselage has no circular curves, it's very geometric.
Has two sets of blades, each with four blades,
one in the rear, one in the front.

Has wings near the back, and smaller ttertiary wings in the
front.
The back wings can each carry four Air to surface missiles.
The front wings can each carry two air to air missiles.

There are two miniguns in the nose, next to eachother.

The blades are comprised of a strong but light moldable
memory metal, this allows them to fold up and be stored
inside the rotor blisters for transport.

Instead of having landing wheels or skids, it has three
retractable legs, one in front two in back.

In the midsection is a heavy weapons bay, there's a door on
the underside that opens for weapons deployment, the primary
weapon used is a M.A.G, Magnetic Acceleration Gun, more commonly
called a RailGun, though it can be fitted with other weapons such
as cannons and in the case of needing a mobile missile launcher,
it could hold an ICBM.

It has a crew of four, a pilot, a sensor operator, a gunner and
a technician.


I'll have to get the pics finished soon, as I don't think a word
description does it justice.

Ok, after final editing I've finished my design, so without further ado.

XH-1 "Heimdall"

(Side View)


(Top View)


(Bottom View)


Because of size editing, and adding on in the last stages,
the blades are'nt even.

I did'nt add any of it's weapons, apart from the minigun in front to it,
so you'l have to more or less imagine them.

The bottom view does'nt have the wings or blades simply because
it did'nt really need them.


So, yeah, this is my submission.

Good effort dude, looks like a high tech schinook (spelling?) with stealth.
Great transport, i think we are aiming at an attack chopper though. Those
two rotors would make it kindof a puff the magic dragon type except a heli.

i think its a good attack helicopter. it wouldnt work in the apache role, but if the heavy weapons bay was filled with long range weapons and it had powerful enough sensors for the long range weapons to be effective then it could be a very deadly attack helicopter. flies in low below radar coverage, shoots off several thousand pounds worth of missiles out of range of enemy defences and then flies back out. so long as it had plenty of speed it could be an extremely useful design.

i think it was the first gulf war when apaches took out the radar stations initially then the tomahawks and f-117s moved in. it would be good in a sort of bomber choper role like that but it could also destroy a lot of tanks with a big weapons bay like that.

Here's my contribution. It still needs some work especially in the landing gear.
