Magnetohydrodynamic drive In concept‚ MHD is attractive because it offers a propulsion system that requires no moving parts. It works on a principle similar to that of an electric motor or generator; that is‚ passing an electrical current through a magnetic field creates a force. In an MHD propulsion system‚ a magnetic field is created within the hull‚ and sea water is used to conduct the electric current‚ as shown in the illustrations accompanying this story. The underlying principle is known

Part 1: Part 2: Parotid salivary gland: It is located by the pharynx and on the cheek. I will remember this because the parotid salivary gland has the key word saliva which is in the mouth. Pharynx: Located in the neck; and‚ I will remember where the pharynx is located because it starts with the letter P which is right across from the parotid salivary gland on the picture. Esophagus: Located in the middle of the body and it is a long tube. I will remember where the esophagus is located because

allow it to move freely but are tight enough not to let air or fluid leak in the barrel. As the pistons move downward‚ a partial vacuum is created inside the barrel. This partial vacuum then draws air past through the carburetor’s throat and into a nozzle that sprays fuel. The mixture of air and fuel in the carburetor is then delivered into cylinders for combustion. The amount of air pulled through partial vacuum created by the pistons is controlled by a throttle valve. The throttle valve is found

Compressed-air engine A Compressed-air engine is a pneumatic actuator that creates useful work by expanding compressed air. They have existed in many forms over the past two centuries‚ ranging in size from hand held turbines up to several hundred horsepower. Some types rely on pistons and cylinders‚ others use turbines. Many compressed air engines improve their performance by heating the incoming air‚ or the engine itself. Some took this a stage further and burned fuel in the cylinder or turbine

air propeller and the helicopter rotor. The first idea of a propulsive airscrew‚ however‚ belongs to J.P. Paucton‚ a French mathematician. Paucton envisioned a flying machine that had two airscrews‚ one for propulsion and the other for sustaining flight. The idea of using an airscrew for propulsion was utilized during the late 1700’s to early 1800’s. Only after experimentation did the inventors conclude that more propulsive power could be obtained by merely straightening out the surface of the airscrew
