A vehicle snorkel is the land-based equivalent of the submarine snorkel which allows submarines to use diesel engines while submerged. [1] Snorkels, when used by vehicles with air-breathing internal combustion engines , sometimes allow limited deep wading capability for river crossing or amphibious landing operations, particularly in the case ...
AIP is usually implemented as an auxiliary source, with the traditional diesel engine handling surface propulsion. Most such systems generate electricity, which in turn drives an electric motor for propulsion or recharges the boat's batteries. The submarine's electrical system is also used for providing "hotel services"—ventilation, lighting ...
However, by 1943 more U-boats were being lost, so the snorkel was retrofitted to the VIIC and IXC classes and designed into the new XXI and XXIII types. The first Kriegsmarine boat to be fitted with a snorkel was U-58, which experimented with the equipment in the Baltic Sea during the summer of 1943. Operational use began in early 1944, and by ...
hobbyist-built DPV with T500 thrusters . A DPV usually consists of a pressure-resistant watertight casing containing an underwater thruster, or a battery-powered electric motor, which drives a propeller The design must ensure that the propeller cannot harm the diver, diving equipment or marine life, the vehicle cannot be accidentally started or run away from the diver, and it remains ...
Placing the cooling radiator section in seawater rather than ambient air allows for the radiator to be smaller. The engine's cooling water may be used directly or indirectly for heating and cooling purposes of the ship. The Stirling engine has potential for surface-ship propulsion, as the engine's larger physical size is less of a concern.
Preparation of microbiological samples in a laminar chamber. A laminar flow cabinet or tissue culture hood is a partially enclosed bench work surface designed to prevent contamination of biological samples, semiconductor wafer, or any particle-sensitive materials.
For an automobile engine the components through which the air flows to the engine cylinders, are collectively known as an intake system [4] and may include the inlet port and valve. [5] An intake for a hydroelectric power plant is the capture area in a reservoir which feeds a pressure pipe, or penstock , or into an open canal.
The flow area then increases for subsonic compression, or diffusion, up to the engine face. The position of the cone within the intake is usually controlled automatically to keep the plane shock wave correctly located just downstream of the throat. Certain circumstances can cause the shock wave to be expelled from the intake.
