By the mid 1960s Jacobson had quit his work in finance to pursue developing his jet ski concept full-time. The first prototype was up and running by 1965. This fixed-handlepole, stand-up design was constructed out of aluminum and powered by a West Bend two-stroke engine driving a Berkeley jet pump.
Johnson had been thinking about a new high-speed design after running into various compressibility problems with the P-38 and the jet engine appeared to solve some of the problems. During 1941 he ordered the development of a new aircraft to be powered by Price's engine, developing the engine as the L-1000 and the aircraft as the L-133 .
In comparison, jet engines and turboprops have TBOs from 3,000 hours up to 16,000 hours or more. [ 4 ] [ 5 ] Since overhauling requires that the engine be disassembled, parts inspected and measured, and many parts replaced, it is typically a labour-intensive and hence expensive operation.
A pump-jet, hydrojet, or water jet is a marine system that produces a jet of water for propulsion. The mechanical arrangement may be a ducted propeller (axial-flow pump), a centrifugal pump, or a mixed flow pump which is a combination of both centrifugal and axial designs. The design also incorporates an intake to provide water to the pump and ...
Control panel for a Boeing 737-800 ECS. In aeronautics, an environmental control system (ECS) of an aircraft is an essential component which provides air supply, thermal control and cabin pressurization for the crew and passengers.

The strength of the vacuum produced depends on the velocity and shape of the fluid jet and the shape of the constriction and mixing sections, but if a liquid is used as the working fluid, the strength of the vacuum produced is limited by the vapor pressure of the liquid (for water, 3.2 kPa or 0.46 psi or 32 mbar at 25 °C or 77 °F). If a gas ...
