Häfeli DH-3
The Häfeli DH-3 was a 1910 Switzerland, Swiss two-seat reconnaissance aircraft, built by the aircraft department of the Federal Construction Works (''Eidgenoessische Konstruktionswerkstaette'', (K+W)) at Thun, Switzerland. Development and design Following the poor performance of the Hafeli DH-2, DH-2, August Häfeli designed an improved version the Häfeli DH-3. It was basically the same airframe as the DH-2, the upper wing had a cutout to give a greater field of fire for the pivoting machine gun. It was a two-bay aircraft of wood and fabric construction, powered by a 120 hp (89 kW) Argus As II water-cooled inline engine. Initial problems with the landing gear and the engine cooling system led to modifications. Further developments were the re-engined and improved DH-3a, and the DH-3b used for engine trials. Following successful trials with an installation of the Handley Page slats all surviving DH-3as were modified in 1932. Operational history On 8 January 1919 a DH-3 ...

Eidgenoessische Konstruktionswerkstaette
''Eidgenössische Konstruktionswerkstätte'' English: "Federal Constructions Works", short K+W, was a Swiss state-owned enterprise, with the aim of making the Swiss military independent of foreign sources for its equipment needs. It was established in 1867 in Thun and produced artillery, vehicles and other typical military equipment. In 1914 Switzerland put in an effort to make itself independent of foreign suppliers of military aircraft and started the production of the DH-1 in Thun. Long-standing connections to the ETH Zurich ensured the necessary know-how. 1940 the aviation department moved from Thun to Emmen (LU) and in 1943 it became a separate unit of the Swiss Armed Forces independent under the name of Eidgenössisches Flugzeugwerk (F+W) (Federal Aviation Works). The Eidgenoessische Konstruktionswerkstaette focused now on the production of armoured fighting vehicles for the Swiss Army, both of its own designs and licensed production of M113 armored personnel carriers and Leo ...

Argus As II
The Argus As II was a six-cylinder, in-line, water-cooled, aircraft engine produced in Germany by Argus Motoren in 1914. The Argus As II produced at 1,350 rpm.Der Argus Flugmotor, 1916 Design and development The Argus As II was a major redesign compared to the preceding Argus 120/130 hp and Argus 140/150 hp six-cylinder engines. Alongside many other changes, the major improvements were the introduction of newly designed steel cylinders and the completely redesigned crankcase, which now had an integrated oil pump and a completely modernized lubrication system. The cylinders were machined from steel separately, with intake and exhaust ducts as well as cooling jackets welded in place in a separate step. While the steel cylinders were still combined to pairs, sharing the same cooling jacket, the change to steel cylinders was accompanied by a change in the design of the intake ducts and the pushrod arrangement. Contrary to the old design, which had the two intake ducts conjo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
