  2. PowerWash Simulator - Wikipedia

    en.wikipedia.org/wiki/PowerWash_Simulator

    PowerWash Simulator is a simulation video game developed by FuturLab and published by Square Enix Collective. Players take control of a power washing business and complete various jobs to earn money. Gameplay primarily revolves around using a power washer to clean dirt off of objects and buildings.

  3. Environmental control system - Wikipedia

    en.wikipedia.org/wiki/Environmental_control_system

    Outflow and pressure relief valve on a Boeing 737-800. Airflow into the fuselage is approximately constant, and pressure is maintained by varying the opening of the out-flow valve (OFV). Most modern jetliners have a single OFV located near the bottom aft end of the fuselage, although some larger aircraft like the Boeing 747 and 777 have two.

  4. Link Trainer - Wikipedia

    en.wikipedia.org/wiki/Link_Trainer

    Link trainer in use at a British Fleet Air Arm station in 1943. The term Link Trainer, also known as the "Blue box" and "Pilot Trainer" [1] is commonly used to refer to a series of flight simulators produced between the early 1930s and early 1950s by Link Aviation Devices, founded and headed by Ed Link, based on technology he pioneered in 1929 at his family's business in Binghamton, New York.

    A pressure washer is used to remove old paint from a boat. Patio flagstones being pressure washed using a rotary nozzle. Pressure washing or power washing is the use of high-pressure water spray to remove loose paint, mold, grime, dust, mud, and dirt from surfaces and objects such as buildings, vehicles and concrete surfaces.

  6. Diverterless supersonic inlet - Wikipedia

    en.wikipedia.org/wiki/Diverterless_supersonic_inlet

    On supersonic jets, the high kinetic energy in the approaching air has to be transformed into static pressure while losing a minimum amount of energy. To do this the inlets are more complicated than subsonic ones as they have to set up two or three shock waves to compress the air. A cone or inclined ramp protrudes ahead of the inlet.

  7. Empennage - Wikipedia

    en.wikipedia.org/wiki/Empennage

    The empennage (/ ˌ ɑː m p ɪ ˈ n ɑː ʒ / or / ˈ ɛ m p ɪ n ɪ dʒ /), also known as the tail or tail assembly, is a structure at the rear of an aircraft that provides stability during flight, in a way similar to the feathers on an arrow. [1] [2] [3] The term derives from the French language verb empenner which means "to feather an arrow ...

  8. Aft pressure bulkhead - Wikipedia

    en.wikipedia.org/wiki/Aft_pressure_bulkhead

    The aft pressure bulkhead or rear pressure bulkhead is the rear component of the pressure seal in all aircraft that cruise in a tropopause zone in the Earth's atmosphere. [1] It helps maintain pressure when stratocruising and protects the aircraft from bursting due to the higher internal pressure.

  9. Zone valve - Wikipedia

    en.wikipedia.org/wiki/Zone_valve

    For electrical zone valves, the motor is often a small shaded-pole synchronous motor combined with a rotary switch that can disconnect the motor at either of the two stopping points ("valve open" or "valve closed"). In this way, applying power to the "open valve" terminal causes the motor to run until the valve is open while applying power at ...
