A CNC-milled, single piece axial compressor blisk. A blisk (portmanteau of bladed disk) is a turbomachine component comprising both rotor disk and blades as a single part instead of a disk assembled with individual removable blades.
In the US 49/563.5 regulatory framework, Event data recorder is defined as a . a device or function in a vehicle that records the vehicle's dynamic time-series data during the time period just prior to a crash event (e.g., vehicle speed vs. time) or during a crash event (e.g., delta-V vs. time), intended for retrieval after the crash event.
AEB systems aim to detect possible collisions with the car in front. [50] This is performed using sensors to detect and classify things in front of the vehicle, a system to interpret the data from the sensors, and a braking system which can work autonomously. [51] Some cars may implement lane departure warning systems. [52]
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 ...
An engine-indicating and crew-alerting system (EICAS) [1] is an integrated system used in modern aircraft to provide aircraft flight crew with instrumentation and crew annunciations for aircraft engines and other systems. On EICAS equipped aircraft the "recommended remedial action" is called a checklist.
It produces engine control software, electronic engine controls (EEC), fuel metering units (FMU), fuel pumps and engine actuators for a large number of common commercial and military aircraft. [1] Together these parts comprise the control system for a jet engine, responsible for delivering the correct amount of fuel and maintaining engine safety.
They are the U.S. counterpart to the UN Regulations developed by the World Forum for Harmonization of Vehicle Regulations and recognized to varying degree by most countries except the United States. Canada has a system of analogous rules called the Canada Motor Vehicle Safety Standards ( CMVSS ), which overlap substantially but not completely ...
The PW 300 series has been developed in partnership with MTU who are responsible for the low pressure turbine. The first variant, the PW305A, has the following configuration and was designed with a core flexible enough for engines with take-off thrusts from 20 kN to 31 kN (4,500 to 7,000 lb): a single-stage fan driven by a three-stage low pressure turbine, supercharging a four-stage axial ...
