Matej, What is APR? I would certainly like to read up on these efforts.Matej said:A lot of info and more designs from Sikorsky and Bell are in APR volume 5 no 5, pg. 30 - 37. They are from NASA papers.
I have to disagree with this statement. This very much looks to me like a project, though it may only be an effort that did not go very far. If this was just a standard reference model, they would have used a fuselage that was nondescript. Frequently models of this type do not have empanage surfaces. This mode has a novel empenage, windows are defined, and it is given an estimated weight class. The fact that the model is mounted on a strut is inconsequential, and in fact common for mounting a force model. I imagine the reason that this was not mounted on a sting is because the sting would have interfered with the empanage flow in a way that would negate the inverted v tail. I think that the real question is not if it is a project, but if it was ever intended a serious study for a production vehicle.Jemiba said:To my opinion, that's not a real project, but (as it is called in the paper) just a rotorcraft drag model,
used to test different configurations on the same basis. The addition of the mounting strut is
another evidence. Nevertheless an interesting paper !
