The pressure at which the control pilot relieves is the functional set pressure of the PORV. When the pilot valve reaches set pressure it opens and releases the pressure from the dome. The piston is then free to open and the main valve exhausts the system fluid. The control pilot opens either to the main valve exhaust pipe or to atmosphere ...
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 HMU has to implement the following: the variable restriction (called the fuel metering valve FMV) and the pressure drop across it (by using a bypass valve between the high pressure fuel pump and the FMV). The pressure drop is kept constant so the fuel flow to the fuel nozzle only depends on the FMV position.
In 2010, Pratt & Whitney proposed the PW9000 medium-bypass engine for the Next-Generation Bomber, using the PW1000G core with a direct-drive fan for a 4:1 bypass ratio. [37] Similar to the PW800, it has the F135 low-pressure section. [38] The Northrop Grumman B-21 Raider is powered by two 27,000 lbf (120 kN) PW9000s. [37] [failed verification]
The "H" model of the B-52 was the only production variant of the heavy bomber to be fitted with turbofan engines, and is the only model remaining in United States Air Force service. It is expected to remain as a mainstay of the Air Force heavy bomber fleet until at least 2040, with options for replacing the 8 TF33 engines with more modern ...
Documents discussed during congressional hearings June 17, 2010, suggested that a battery in the device's control pod was flat and that the rig's owner, Transocean, may have "modified" Cameron's equipment for the Macondo site (including incorrectly routing hydraulic pressure to a stack test valve instead of a pipe ram BOP) which increased the ...

The high-pressure (HP) compressor operates at up to a 22:1 compression ratio, which is roughly double the corresponding value for the CFM56's HP compressor. [ 7 ] CFM uses ceramic matrix composites (CMC) to build the turbine shrouds. [ 8 ]
