The USAF standardized definition of STOL is an aircraft with the ability to clear a (50 / 100 / 200) foot obstacle within (1,000 / 1,500 / 2,000) feet of commencing takeoff role and to stop within (500 / 1000 …

Military Helicopters - an overview | ScienceDirect Topics

Feb 5, 2015 · The aim of this paper is to investigate the dynamic stability characteristics of compound helicopters and compare the results with a conventional helicopter. The paper discusses the …

But with the higher speeds come the problems of retreating blade stall and increased rotor stress. Generally, the way around this has been to offload the rotor by adding a wing. However you …

Feb 4, 2016 · Considering all three rotorcraft types, there are more compelling opportunities and payoffs for compound helicopter R&D than for helicopters and tiltrotors. Along with the need for compound …
