The image shared by sferrin did not quite depict the XCH-62A but some other Boeing Vertol concepts.
We already had it here:
I have therefore moved the post to that topic.
A recent donation of Army Aviation material to the Museum has delivered some Boeing Vertol HLH material to add to this thread. I have some photos of a briefing room for an HLH presentation I need to scan - walls are covered in prints, vuegraphs and artwork and there are a number of models in the images as well. I'll post those once I get them scanned. In the meantime here's two trifold brochures on the HLH. I don't know which was published/printed first - I find it interesting one is Boeing Vertol Company and the other just Boeing.
The donor was heavily involved in the acquisition process for the HLH and for the AH-56 - we will be interviewing him in about a month and the subject of just what the HLH/XCH-62 at Ft. Rucker was (mock up, test rig, prototype) is on my list of questions.
Going through a friends estate, I found the Aircraft Geometry Basic Points drawing for the Model 301.
I looked through this topic and did not see this drawing in the previous posts.
I see Scott is trying to sell the inboard profile, so won't post my scans.
