Vietnam Airlines Flight 831, a Tupolev Tu-134, crashed in a rice field 6 kilometres (3.7 miles) N of Bangkok International Airport, while operating a flight from Hanoi, Vietnam to Bangkok, Thailand, on 9 September 1988.
Rolls-Royce based the ten-stage high-pressure compressor on an eight-stage run in the RB401 in the mid 1970's followed by a nine-stage run in the RJ.500. The V.2500 would use ten stages, with the first four with variable stators, giving a pressure ratio of 20:1. [4] A single-stage booster was also part of the original configuration.
9 September 1988: Vietnam Airlines Flight 831, a Tupolev Tu-134 (built in 1978), registration VN-A102, departed from Hanoi with 81 passengers aboard and crashed while on approach to Bangkok. There were 76 fatalities and the aircraft was entirely destroyed. The aircraft flew into a heavy thunderstorm and was probably struck by lightning.

Air compressor supplies air into a nail gun.. An air compressor is a machine that takes ambient air from the surroundings and discharges it at a higher pressure. It is an application of a gas compressor and a pneumatic device that converts mechanical power (from an electric motor, diesel or gasoline engine, etc.) into potential energy stored in compressed air, which has many uses.
Compressor characteristic is a mathematical curve that shows the behaviour of a fluid going through a dynamic compressor. It shows changes in fluid pressure, temperature, entropy, flow rate etc.) with the compressor operating at different speeds. A compressor increases the pressure of a fluid passing through it, so that the exit pressure is ...
Consequently, air treatment identical to that used for an oil-flooded screw compressor is frequently required to ensure quality compressed air. In small piston compressors carpenters homeowners sometimes use "oil free" compressors in which oil free is a reference to not using oil but Teflon type of coatings permanently adhered to wear surfaces.
The choice of working fluids is known to have a significant impact on the thermodynamic as well as economic performance of the cycle. A suitable fluid must exhibit favorable physical, chemical, environmental, safety and economic properties such as low specific volume (high density), viscosity, toxicity, flammability, ozone depletion potential (ODP), global warming potential (GWP) and cost, as ...
