An illustration of several key components in a typical four-stroke engine. For a four-stroke engine, key parts of the engine include the crankshaft (purple), connecting rod (orange), one or more camshafts (red and blue), and valves. For a two-stroke engine, there may simply be an exhaust outlet and fuel inlet instead of a valve system.
This is the case on many large aircraft such as the 747, C-17, KC-10, etc. If you are on an aircraft and you hear the engines increasing in power after landing, it is usually because the thrust reversers are deployed. The engines are not actually spinning in reverse, as the term may lead you to believe.
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 ...
ecu.test automates the control of the whole test environment and supports a broad range of test tools. Various abstraction layers for measured quantities allow its application on different testing levels, e.g. within the context of model in the loop, software in the loop and hardware in the loop as well as in real systems (vehicle and driver in the loop).
This type of compressor is used in gas turbine engines, for supercharging reciprocating engines and for industrial processes, where it is known as a dynamic compressor. A map is created from compressor rig test results or predicted by a special computer program. Alternatively the map of a similar compressor can be suitably scaled.
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 type of jet engine used to explain the conversion of fuel into thrust is the ramjet.It is simpler than the turbojet which is, in turn, simpler than the turbofan.It is valid to use the ramjet example because the ramjet, turbojet and turbofan core all use the same principle to produce thrust which is to accelerate the air passing through them.
ISO 8178 is a collection of steady state test cycles used for defining emission standards for non-road engines in the European Union, United States, Japan and other countries. Test cycle ISO 8178 C1 is also referred to as "Non-Road Steady Cycle" and used extensively. The Non-road Transient Cycle is supplementing it in some modern emission ...
