The engine was an upgraded version of the slightly smaller HL210 engine which was used to equip the first 250 Tiger I tanks built, and which had an aluminium crankcase and block. The earlier HL210 engine had a displacement of 21.353 L (1,303.0 cu in) or 1,779 cm³ per cylinder; bore 125 mm (4.9 in), stroke 145 mm (5.7 in).
Larger examples were built as multiple rows. As each row contains an odd number of cylinders, to give an even firing sequence for a four-stroke engine, an even number indicates a two- or four-row engine. The largest of these was the Lycoming R-7755 with 36 cylinders (four rows of nine cylinders), but it did not enter production.
The WU "First Model", also known by Whittle as the first "experimental" engine, [1] and the "1st edition", [2] was the first turbojet engine to be built and run in the world. [3] Although an experimental engine and not intended for flight it was designed to be very light by normal engineering standards. [ 2 ]
An engine test stand is a facility used to develop, characterize and test engines. The facility, often offered as a product to automotive OEMs , allows engine operation in different operating regimes and offers measurement of several physical variables associated with the engine operation.
The Pearl engine was developed in Dahlewitz from the BR700 with Advance2 technologies. [16] EASA certification was applied for on 28 February 2015. [9] It made its first ground run in 2015, type tests in 2016, and flight tests in 2017. [17] Six test engines logged over 6,000 cycles on 2,000 test hours. [18]
In a number of cases, especially the dry sump tank engines (e.g. the HL108 TR), this is the complete designation of an engine: in other words, there is no factory-fitted clutch (K) attached to the engine; no extra drive belts driving a compressor (R) and/or dual fans (RR) on custom pulleys; ignition is achieved by a magneto driven off the ...
These engines were produced from 1987 through 2009. Ranging from 1.3 L up to 1.6 L, these four-cylinder engines were built with lightness in mind, featuring a hollow crankshaft and camshaft, and the weight of a four-cylinder engine (1.3 L HC) is similar to the 1.0 L three-cylinder CB engines. [1]
The engine was first tested on the Pratt & Whitney Boeing 747SP on July 11, 2008 through mid-August 2008, totaling 12 flights and 43.5 flight hours. [14] It then flew starting October 14, 2008 on an Airbus A340-600 in Toulouse on the number two pylon. [15] Testing of the CSeries bound PW1524G model began in October 2010. [16]
