ABC Wasp II
The ABC Wasp was an experimental 170 hp (127 kW) seven-cylinder radial engine designed by the noted British engineer Granville Bradshaw, and primarily built by ABC Motors Limited. An order for twelve experimental ABC Wasp engines was placed with Guy Motors on 19 April 1918. Eight ABC Wasp engines were made by Crossley Motors Ltd of Manchester, England. Design and development The ABC Wasp was one of the first large non-rotary air-cooled radials. At a weight of 290 pounds (131 kg), it had a reasonable power-to-weight ratio at 0.6 horsepower per pound. This World War I–era engine is noteworthy because it was one of the first in which the cylinders were coated with copper in an attempt to dissipate heat. The ABC Wasp never evolved beyond the experimental stage, but it was the predecessor of the unsuccessful Dragonfly engine.

Radial Engine
The radial engine is a reciprocating engine, reciprocating type internal combustion engine, internal combustion engine configuration in which the cylinder (engine), cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized Star polygon, star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings ar ...

BAT Bantam
The BAT F.K.23 Bantam was a British single-seat fighter biplane produced by British Aerial Transport Company Limited of London during World War I. Design and development Frederick Koolhoven's first design for the British Aerial Transport Company (BAT) was the F.K.22 single-seat fighter. It was a two-bay biplane of wooden construction. It was planned to have a 120 hp (90 kW) A.B.C Mosquito radial engine but the failure of this engine led to the installation of the 170 hp (127 kW) A.B.C.Wasp I in the first and third aircraft. The second machine was fitted with a 100 hp (75 kW) Gnome Monosoupape rotary engine and was the first to fly at Martlesham Heath in January 1918. The original contract called for six development aircraft but three aircraft were built as the F.K.23 Bantam I, the second prototype then being renamed the Bantam II. The Bantam I was the same wooden structure but was slightly smaller. Two further prototypes of the larger des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1910s Aircraft Piston Engines
Year 191 ( CXCI) was a common year starting on Friday of the Julian calendar The Julian calendar is a solar calendar of 365 days in every year with an additional leap day every fourth year (without exception). The Julian calendar is still used as a religious calendar in parts of the Eastern Orthodox Church and in parts .... At the time, it was known as the Year of the Consulship of Apronianus and Bradua (or, less frequently, year 944 ''Ab urbe condita''). The denomination 191 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
