Abstract:

The purpose of this document is to present a comprehensive, in-depth review of the serious efforts made in the development of VTOL and V/STOL concepts and aircraft other than the helicopter. The time period covered is from the beginning of organized government-sponsored activity in the late 1940's through the present, during which a very large study and development activity has taken place. Conventional helicopters are not included because their development history is a sizeable subject in itself and one which is already well-documented. Included are V/STOL aircraft which do use rotors but are aimed at providing cruise speeds and aerodynamic efficiencies similar to those of conventional airplanes. Although not aircraft in the conventional sense, wingless VTOL vehicles which use direct thrust (rocket or turbojet/turbofan) for lift in all flight modes also are included since such machines do have a close relationship to some of the more commonly accepted forms of VTOL aircraft. This volume contains an introductory review of V/STOL aircraft concepts and the rationale behind them. The concepts are categorized by propulsion system. This volume contains definitive information and technical reviews of the rocket belt, turbojet/turbofan platform type (wingless) vehicles, and turbojet/turbofan vertical attitude takeoff and landing aircraft.

Thanks Mirek.

With the developments in composite construction and electronics etc. perhaps one or more of these ideas may eventually become feasible.

My thought - exactly ..... :)

Thank you for this article msmfi I have not read all of it but hope to some day,

My interests have always been captured by designers who try to get off the ground as soon as possible in runways as short as possible .... who cares if it is rotary wing or fixed wing.

My thought - exactly ..... :)

I've been looking around at some concepts beeing persued.And to be truthfull I don't know why the self rotating wing has not been persued with the same vigor.It has to be the most practical of Ideas.Simple (could make a controled decent with only one motor) since one does not effect the other.Look at my 1st prototype at r/cuniverse charlie111 I have since changed the direction of Rotation allowing me to run stock rotation on both wing motors and getting similar airflows.This may not be a High Speed vehicle But, most people want to travel at safe speeds which are relatively slow.I've given some thought to a Versitile use of the Concept.Something Similar to a Roll Cage that could be Driven into with a Small Electric Car a (Smart Car).It could then use the Cars Power Supply and be stored when not in use.Rather than trying to fold wings away that would be as Large as Todays Gliders!I may work on new Protoype today Going to have get some film of it in flight.Had problems finding Reverse props for 1st prototype.It still lifted with wrong rotation on one side.Im sure performance will be much better with this change in direction!! so (Roll Over Sigorski) and let me give you the news!

Great stuff, Mirek, what a wealth of engineering unfolds before us in these pages!
