The Uhu was first flown in July 1938 and entered service with the Luftwaffe from 1940 as a short-range reconnaissance and army co-operation aircraft. Armament comprised four 7.9mm machine-guns and two or four 50kg bombs. The central crew nacelle, projecting rearwards between the twin tailbooms, was extensively glazed and provided excellent all-round vision for the crew of three. Operated mainly on the Eastern Front, the Uhu remained in production until 1944, by which time nearly 850 aircraft had been completed, including a number of purpose-built five-seat trainers. However, because of the low speed of the aircraft, its use was subsequently restricted to less active duties, such as evacuation of wounded, radio training and communications.

| elroto, jose_tassara(@)hotmail.com, 31.10.2008 I believe that there is a conserted effort to restore an owl back to airworthy condition somewhere in Russia. | | Richard Stankiewicz, two_av8(@)hotmail.com, 13.11.2007 The vanes are part of the constant speed feature of the propeller. The fins are attached to the spinner and is free to spin,the spinner is attached to a small oil pump.
The oil pressure adjusts propeller pitch, if the load on the propeller increases ie during climpb, the pressure falls and the pitch is decreased (fine pitch). Hope this helps | | Kenneth Mitchell, kcmitch(@)frontiernet.net, 11.09.2007 What was the purpose of the strange looking spinners on the props? Was there a purpose for the little vanes on the front of them? Thanks for your time in this matter.
ken | | Gerry Jarvis, jarvisg(@)telusplanet.net, 17.12.2006 Question for anyone with either very specialized knowledge or a good educated guess... Of what aerodynamic benefit are the triangular vanes affixed to the Uhu's prop spinners? Are they maybe part of a constant-speed or pitch-change mechanism? Seems they'd disturb airflow right at a bad place for disturbed airflow. Anyone have any ideas? |
