A major part of the torque is due to friction, so the differences in friction can cause large variations of the preload with the same torque setting; [3] angle-controlled tightening (also known as turn-of-the-nut method) is a technique where the bolt joint is rotated to some angle that ensures the stress beyond the yield limit of the parts ...
The Continental O-170 engine is the collective military designation for a family of small aircraft engines, known under the company designation of A50, A65, A75 and A80. The line was designed and built by Continental Motors commencing in the 1940s.
The Continental O-190 (Company designations C75 and C85) is a series of engines made by Continental Motors beginning in the 1940s. Of flat-four configuration, the engines produced 75 hp (56 kW) or 85 hp (63 kW) respectively. [1] The two variants shared the same bore, stroke and compression ratio.
The Continental IO-360 is a family of fuel-injected air-cooled, horizontally opposed six-cylinder aircraft engines manufactured by Continental Motors in the United States of America, now part of AVIC International since 2010. [1] [2] The engine is available in both naturally aspirated, fuel injected IO-360 models and turbocharged TSIO-360 ...
Light aircraft commonly use flat-four engines with displacements up to 6.4 L (390 cu in) from manufacturers such as Rotax, Lycoming Engines, Continental Motors and Franklin Engine Company. For radio-controlled aircraft, flat-four engines with displacements of 40–50 cc (2.4–3.1 cu in) are produced by companies such as O.S. Engines.
The C90 was introduced in 1947 as a follow-on to the A65, which had been in production since 1939. [7] [8] Many of the designs powered by the C90 are upgraded variants of earlier A65 powered designs, such as the Piper J-3 Cub and PA-11 Cub Special, [9] Aeronca 7AC, [3] and Luscombe 8A. [10] The engine was developed from the earlier O-190 by increasing the stroke 1 ⁄ 4 inch.
Continental O-300 engine installation in a Cessna 172. The C-145 was developed from the 125 hp (93 kW) C-125 engine. Both powerplants share the same crankcase, although the C-145 produces an additional 20 hp (15 kW) through a longer piston stroke, higher compression ratio of 7.0:1 and different carburetor jetting.
The Continental O-470 engine is a family of carbureted and fuel-injected six-cylinder, horizontally opposed, air-cooled aircraft engines that were developed especially for use in light aircraft by Continental Motors. Engines designated "IO" are fuel-injected.
