The A320 engine, the PW1100G, had made its first static engine test run on November 1, 2012, [20] and was first tested on the 747SP on May 15, 2013. [21] The first flight of the Airbus A320neo followed on September 25, 2014. [22] The PW1100G engine achieved FAA type certification on December 19, 2014. [23]
The YF119-PW-614 on the X-32 had a pitch-axis thrust vectoring nozzle and valves can redirect the engine exhaust and bleed air to provide direct lift, similar to the Pegasus engine on the Harrier. In contrast, YF119-PW-611 on the X-35 had a round axisymmetric nozzle that can swivel downwards while the low-pressure spool drives a lift fan that's ...
The JT8D is an axial-flow front turbofan engine incorporating a two-spool design. There are two coaxially-mounted independent rotating assemblies: one rotating assembly for the low pressure compressor (LPC) which consists of the first six stages (i.e. six pairs of rotating and stator blades, including the first two stages which are for the bypass turbofan), driven by the second (downstream ...
The Pratt & Whitney PW4000 is a family of dual-spool, axial-flow, high-bypass turbofan aircraft engines produced by Pratt & Whitney as the successor to the JT9D.It was first run in April 1984, was FAA certified in July 1986, and was introduced in June 1987.
The first flight with one of these engines took place on 22 February 2007, using a Boeing 747-100, fitted with one GEnx engine in the number 2 (inboard left hand side) position. By fall 2019, General Electric was offering the GEnx-2B, developed for the 747-8, for the revised 767-XF variant based on the 767-400ER, but needed enough volume to ...
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]
The engine performance deteriorates with use as parts wear, meaning the engine has to use more fuel to get the required thrust. A new engine starts with a reserve of performance which is gradually eroded. The reserve is known as its temperature margin and is seen by a pilot as the EGT margin. For a new CFM International CFM56-3 the margin is 53 ...
The original plans called for 17 prototype test engines to be built. The first test engine consisted of only the core module (named " Kabini ", a major tributary and often cited starting point of the Kaveri river), while the third engine was the first example fitted with variable stator vanes on the first three compressor stages.
