Submarine “Afalina”. Building a hydrofoil boat

The hydrofoil “Afalina” is intended for walks and short (one or two days) trips on the big rivers and reaches where the probability of a meeting with the developed excitement is high. With the outboard motor capacity of 20-30 HP the boat can be used as a towing water skier for practicing elements of figure […]

steam Deck machinery


A steam engine is a heat engine of external combustion that converts the energy of water vapor into mechanical work of reciprocating piston motion, and then into rotational motion of the shaft. In a broader sense, a  engine is any external combustion engine that converts  energy into mechanical work. The first  engine built in the […]
