AH-1 Apache
Posted on 10/15/2015 3:57:44 AM PDT by Utilizer
The AH-64A/D Apache and AH-64E Block III Apache Longbow (renamed Guardian) are four-blade twin-engine attack helicopters manufactured by Boeing. The Apache was originally developed by Hughes Helicopters in the 1970s (first flight on September 30, 1975), however, the company was acquired by McDonnell Douglas in 1984. In 1997, McDonnell Douglas merged with Boeing.
The latest variant, the AH-64E Apache Guardian helicopter (originally designated AH-64D Block III), is powered by two General Electric T700-GE-701D turboshaft engines with 1,994 shp each. The AH-64D/E models are based on the original AH-64A, which was deployed in 1984 and first used in combat in 1989 in the U.S. military operation in Panama. Between 1984 and 1997, Boeing produced 937 AH-64As for the U.S. Army, Egypt, Greece, Israel, Saudi Arabia, and the United Arab Emirates. The combat-proven AH-64A is still in service.

Winter will be here soon, and I have recently become interested in scale-model aircraft. I want to build a custom scale-model AH-64A/D helo in the next several months, and am looking for a site where I can download drawings for the build(s), with the final dimensions to be determined when a suitable powerplant is selected for the craft.
I might be tempted to build an AH-1W SuperCobra instead depending upon drawing availability.
Any FReeper help would be appreciated.

That’s an AH-64D.
I do know that aircraft may be a bit under-powered with that engine as (like the Black Hawk) more weight has been added to the airframe over the years.
Problem is there is at present no gas turbine between the SHP-range of 2,000 and 4,500 - they need 3 - 3.5K for peak performance.
Could be an AH-64E since it also has the radome. The photo does not specify.

If you may have or know someone with Solidworks or another 3D parametric program, GrabCad has some downloadable files you can get going with. I did a search on both. Didn’t find anything on the Cobra.

Thanks, I will look into it. I currently only have one line-drawing (simple wireframe) of an AH-64A Apache, but it does not translate well into the current 3D CAD programs I own and there are no dimensions given. Your link is quite helpful, mate.
It’s an old stock photo of an AH-64D.
You are probably right. Can’t tell if it has the upgraded landing gear or not, and it is the default pic on the Boeing website so it’s possible.
You’re welcome. The thing about these files is that they can also be translated into stl files for 3D printing. I use a company near Detroit that uses a laser sintering process of a fiberglass/nylon material that produces very strong parts. Naturally, all the files are salable as well.
Make that scaleable, not salable.
Really. What’s their minimum for a single/short run and turnaround average, d’ya know? I might be able to use them in the future, depending.
You could buy a 1/48 or 1/72 static model from Revell or Academy and then take measurements off of it to scale up to your RC model.
There should be a Flightgear 3D sim model of the AH-64 somewhere on line. Maybe there is one at FGUK. Some Flightgear models are quite good, while others are kind of crude.

I thought of that, but that would mean I would have to take it as a given that their models were accurately to scale. In other words, I would be creating a model from a model -a copy of a copy then. Not really certain that is the most accurate method of proceeding plus some detail would be lost.
Based on your comments, I predict you’ll never build it.
Quite sure I will build something that looks like it, with the first build about the size of an R/C plane for ease of construction and as a prototype. Hopefully the second and third builds will have provided enough experience that I can construct a flyable version.
Time will tell.
When you believe the product of professional modelers is unworthy of your consideration, you have lost sight that you are simply building a toy.
What caused you to assume I was simply building a toy? No, the intent once I have some experience in constructing some prototype models is to build at least one and probably more flyable ones. I used to be quite heavily into R/C cars and am now looking to build actual working scale-model R/C helos and perhaps an aircraft or two.
If I wished to attain a toy to admire that is one thing, but I intend to construct at least a moderately functional flying craft. Slow, but with a lot of lift to more easily get off the ground, and stable as well.
I still remember many years ago that one flyable B-24 Liberator that was demonstrated at some large R/C meet. Everything to scale, and four functioning engines.
Didn’t fly all that well, but it certainly looked good on the tarmac and the few times it was able to take off and land. Thinking of doing roughly the same with the small craft I am intent on constructing.
Might even throw together a small program for the computer to fly simple patterns with it in time.
