divergent nozzle การใช้

• Robotic oxy-fuel cutters sometimes use a high-speed divergent nozzle.
• VASIMR has been described as a convergent-divergent nozzle for ions and electrons.
• This includes convergent and convergent-divergent nozzles that may be fixed or geometrically variable.
• For a supersonic flight Mach number, acceleration is typically achieved via a convergent-divergent nozzle.
• The divergent nozzle may be an integral part of the afterburner nozzle petal, an angled extension after the throat.
• Thrust is provided by the combustion products exiting the engine at high velocity, via a fixed area ratio convergent-divergent nozzle.
• Rocket motors maximise thrust and exhaust velocity by using convergent-divergent nozzles with very large area ratios and therefore extremely high pressure ratios.
• Using a convergent / divergent nozzle gives more force since the exhaust also presses on it as it expands outwards, roughly doubling the total force.
• Combustion in a ramjet takes place at subsonic velocities, similar to turbojets, but the combustion products are then accelerated through a convergent-divergent nozzle to supersonic speeds.
• A de Laval nozzle has a convergent section followed by a divergent section and is often called a convergent-divergent nozzle ( " con-di nozzle " ).
• In order to increase speed for supersonic flight, fuel was injected into the engine exhaust, upstream of a divergent nozzle similar to that seen on a rocket engine.
• The " F " indicated it was fitted with the VK-1F engine with an afterburner by modifying the rear fuselage with a new convergent-divergent nozzle and fuel system.
• The second phase of the engine is a strong electromagnet positioned to compress the ionized plasma in a similar fashion to a convergent-divergent nozzle that compresses gas in traditional rocket engines.
• Unique PW1120 components included a wide chord low pressure ( LP ) compressor, single-stage uncooled low pressure ( LP ) turbine, simplified single stream augmentor, and a lightweight convergent / divergent nozzle.
• The obvious result is that in order to accelerate a flow to supersonic, one needs a convergent-divergent nozzle, where the converging section accelerates the flow to sonic speeds, and the diverging section continues the acceleration.
• This motor introduced a series of innovations for the Chinese solid motor industry : first use of glass fibre wound cases, carbon / carbon nozzle throat insert material, contoured divergent nozzle, and non-destructive test of the motor grain.
• The second aircraft, Ye-152-2, was returned to Mikoyan for conversion to the Ye-152M, featuring an axi-symmetric convergent divergent nozzle and canards on either side of the forward fuselage, which were soon removed.
• When the pressure ratio across a convergent nozzle exceeds a critical value, the flow " fixed " convergent-divergent nozzle used on a conventional rocket motor, those on turbojet engines must have heavy and expensive variable geometry to cope with the great variation in nozzle pressure ratio that occurs with speeds from subsonic to over Mn3.
