Model rocket motor classification. Motors for model rockets [1] and high-powered rockets [2] (together, consumer rockets) are classified by total impulse into a set of letter-designated ranges, from ⅛ A up to O. The total impulse is the integral of the thrust over burn time. Where is the burn time in seconds, is the instantaneous thrust in ...
An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum operating temperature to the maximum operating temperature (or peak operating ...
In electrical and safety engineering, hazardous locations (HazLoc, pronounced haz·lōk) are places where fire or explosion hazards may exist. Sources of such hazards include gases, vapors, dust, fibers, and flyings, which are combustible or flammable. Electrical equipment installed in such locations can provide an ignition source, due to ...
Insulation system. The electrical insulation system for wires used in generators, electric motors, transformers, and other wire-wound electrical components is divided into different classes by temperature and temperature rise. The electrical insulation system is sometimes referred to as insulation class or thermal classification.
A Cylinder Head Temperature gauge (CHT) measures the cylinder head temperature of an engine. Commonly used on air-cooled engines, the head temperature gauge displays the work that the engine is performing more quickly than an oil or water temperature gauge. As the engine works at high speed or uphill, head temperature will increase quickly.
There was also a basic bus, with an inline-4 inclined 1.8 carburetor engine. The 1.8 carb motor was a Golf-derived motor, fitted into the bus like an inline-4 diesel in a T3. Called the "Volksie bus", it was a basic bus, with steel 15" rims, single round headlights, steel wrap-around bumpers, and with no aircon or PAS.
The Learjet 25 is a challenging aircraft to fly in comparison with most general aviation aircraft and more modern light jets. Pilot workload is high and approach, landing and takeoff speeds are above average for civilian aircraft. The Learjet 25 also requires long runways at high altitude or ambient temperature.
The R-15-300 was designed at the OKB-300 design bureau led by Sergei Tumansky in the late 1950s. The engine was originally intended for the Tupolev Tu-121 high-altitude high-speed cruise missile. Due to a lack of Soviet resources and funding the engine casing was mainly steel, and in areas exposed to high temperatures, 30 micrometre silver ...
