Product features include an ergonomic handle with plastic-coated grip; retractable stabilizer bar and integral air-pressure gauge; dead-man trigger with trigger guard to prevent accidental actuation; oversized trigger and trigger guard to allow room for triple layered linesman gloves; insulated, 4-foot fiberglass barrel rated up to 300kV; internal high pressure air hose within barrel acts as pressure boundary; non-sparking bronze barrel hardware; adjustable, thermoplastic spray shield (or just spray shield); non-sparking, bronze supersonic nozzle; extensions available in 2-, 3-, 4- and 5-foot lengths; 1/4-inch FNPT air inlet; and Chicago-style swivel connector.
They feature patented supersonic nozzles that utilize compressed-air to produce highspeed laser-like jets that move at twice the speed of sound for faster, more effective digging in the toughest soils.
The model scramjet combustor is directly mounted downstream the supersonic nozzle of the air heater which heats the air by means of air/ethanol/[O.sub.2] combustion.
The system that is used to perform the process consists of a gas control module that regulates the high-pressure gas; a gas heater; a powder feeder; the supersonic nozzle; and a data acquisition and control system.
This stream then passes through a supersonic nozzle to produce a low supersonic flow entering the MHD accelerator.
In other words, this high temperature zone downstream of the nozzle exit is responsible for reducing the lean limit of the main chamber mixture by using a supersonic nozzle.
A standard, portable air compressor powers the AIR-VAC with superior performance due to use of the patented supersonic nozzle in the injector.
This knowledge is crucial to explain how supersonic nozzles can extend the lean flammability limit compared to straight nozzles.
If the blow pipes can be removed, then this company's supersonic nozzles can replace the old cleaning systems.
They confirm the sudden chemical freezing in supersonic nozzles. However, no observation is reported on any non-equilibrium in calorimetric evolutions.
