Good Day All.
I have found on the following paper available on the UK CAA website
CAA Paper 2009/02: The Aerodynamics of Gyroplanes
The link is
http://www.caa.co.uk/application.aspx?c ... il&id=4184
This report describes research work undertaken for the Civil Aviation Authority by the University of Glasgow between November 1993 and June 2008 under the study entitled Aerodynamics of Gyroplanes, instigated by the 1991 Air Accidents Investigation Branch (AAIB) review of the airworthiness of Air Command series of gyroplanes. Elements of this study include analytical, wind tunnel and flight test activities. Research included the comparison of a mathematical model of the aircraft validated against actual flight test data. The Report also presents results from a number of associated studies, a literature review, a study of teeter margin, an assessment of blade flexibility on rotor and aircraft stability and a review of BCAR Section T.
It gives a overview of many things i.e. thrustline, tailplanes and sizes etc. It is a hefty paper of approx 365 pages but should be interesting reading matter, in understanding what is required in Gyro design, certification etc.
Greetings and fly safely
