TAF VIII-2, four-seater Tandem Airfoil Flairboat Typ Jörg II, built in 1983. Following the F&E and test period, Dipl. Ing. Günther Jörg was awarded with the "Phillip Morris Scientific Award" for the Transportation System for the future. Another TAF VIII-2, built in 1994 was given to a Japanese private citizen.
Ekranoplan A-90 Orlyonok. A ground-effect vehicle (GEV), also called a wing-in-ground-effect (WIGE or WIG), ground-effect craft/machine (GEM), wingship, flarecraft, surface effect vehicle or ekranoplan (Russian: экранопла́н – "screenglider"), is a vehicle that is able to move over the surface by gaining support from the reactions of the air against the surface of the earth or water.
The airfoil was a NACA 22 wing section, with a thickness-to-chord ratio of 19.5% at the root tapering to 12% at the tip. [ 19 ] The wing possessed great structural strength, provided plenty of room for fuel tanks and a heavy armament, while allowing the aircraft to be a steady gun platform. [ 20 ]
[43] [nb 8] The first major problem experienced during the first few flights was serious engine vibrations, which were cured by replacing the rigid, eight-point engine mountings with six-point rubber-packed shock mounts. In a further attempt to alleviate engine vibration, the four-blade propeller was replaced with a five-blade unit; eventually ...
The effect of airfoil geometry on dynamic stall is quite intricate. As is shown in the figure, for a cambered airfoil, the lift stall is delayed and the maximum nose-down pitch moment is significantly reduced. On the other hand, the inception of stall is more abrupt for a sharp leading-edge airfoil. [8] More information is available here. [13]
[65] [66] Difficulties with its avionics and the MA-8 fire-control system were experienced early on; typically the F-105 required 150 hours of maintenance for each flying hour. Most of these problems were addressed under Project Optimize. The lack of spares resulted in the entire F-105B fleet being briefly grounded in 1960.
An adaptive compliant wing is a wing which is flexible enough for aspects of its shape to be changed in flight. [1] [2] Flexible wings have a number of benefits.Conventional flight control mechanisms operate using hinges, resulting in disruptions to the airflow, vortices, and in some cases, separation of the airflow.
The Canadair CP-107 Argus (company designation CL-28) is a maritime patrol aircraft designed and manufactured by Canadair for the Royal Canadian Air Force (RCAF). [3] The Argus served throughout the Cold War in the RCAF's Maritime Air Command and later the Canadian Force's Maritime Air Group and Air Command.
