Hi,

the Flugwissenschaftliche Vereinigung Aachen established in 1920,continue to this days,the
first project after the WWII was is No.14;

FVA-14 Ring-wing light aircraft,The first project at the FVA after WWII was the FVA-14 Ringflügel, a disc / annular wing aircraft, construction of which began in 1952. Built to investigate the theoretical advantages of a ring wing the FVA-14 was first flown in scale model form, with some success, then wind tunnel tests revealed serious problems with stability which were insurmountable. Work was abandoned and the completed un-flown prototype was stored in a workshop at Aachen where it was broken up to make room for other work.

FVA-15 : this project was instigated to research the use of compressed air for creating control forces om glider wings. Developed by Dr.-Ing. H. Stein the system used air blown through slots over the upper surfaces of a wing to produce lift for control purposes. A Grunau Baby III was modified with roll control slits for testing, retaining normal aileron control for safety purposes. Blown compressed air control systems were found to be feasible, but require a high volume/mass flow air supply to be practical, ruling out their widespread use in gliders.

FVA-27 : Since the Wright brothers started flying at Kill Devil Hill aircraft designers have recognised that canard aircraft are intrinsically more efficient than conventional aircraft and can also have safety benefits. Students at the FVA have initiated a project to design and build a canard glider to meet standard class competition rules demonstrating significant performance gains over comparable standard class gliders. The FVA-27 is a canard glider constructed from CFK (Carbon-fibre/Kevlar) with a welded steel tube truss fuselage structure

Thank you Stevoe,

and here is anther projects;

FVA-28 Being a project of central importance over multiple years, the large workshop of the FVA in Würselen near Aachen has been named FVA-28 as an official project. It is vital in repair and maintenance of the sailplanes as well as offering space and facilities for research projects.

FVA-29 The current research project of the FVA is the design and build of an electro-turbo to fit into the club-owned ASW28-18 sailplane. The projects includes both structural and electronic components as well as the pilot interface.

FVA 30 is the latest project of the FVA and also revolves around the electrification of aviation. As a follow-up project to the FVA 29, we can build on the knowledge gained and will further increase the knowledge of the FVA in the field of electric flying.

In short, the text says, that this was a model for testing the flight characteristics of a ring wing,
as one of the first research projects after WW II, in the hope to achieve significant reductions in
structural weight. Work on it was led by Engineer J.Herrmann. The successful flights of this model
triggered the construction of a full sized ring wing, though calculations and wind tunnel testing
couldn't be accomplished before 1955, when the project was cancelled and the unfinished prototype
destroyed after two years of storage. So, we are back at what you found out about the FVA-14 and
it actually was a project. ;)
