An engines horsepower‚ in its most condensed definition‚ refers to the amount of horses it would take to perform the same function. At mankind’s present level of dependence on technology such a concept seems absurd‚ but at the beginning of the 17th century the literal equation of horsepower was used daily‚ especially in industry. With wind or water as the only alternative power sources‚ the use of load bearing beasts was inevitable. Wind is inconsistent and unreliable‚ whereas water was only plausible

Piston Engines Picture a tube or cylinder that holds a snugly fitting plug. The plug is free to move back and forth within this tube‚ pushed by pressure from hot gases. A rod is mounted to the moving plug; it connects to a crankshaft‚ causing this shaft to rotate rapidly. A propeller sits at the end of this shaft‚ spinning within the air. Here‚ in outline‚ is the piston engine‚ which powered all airplanes until the advent of jet engines. Pistons in cylinders first saw use in steam engines. Scotland’s

The Jet Engine and the Revolution in Leisure Air Travel‚ 1960-1975 Peter Lyth Air transport for European tourists got off to a shaky start in the late 1920s. 1 But it was to be thirty years before leisure air travel was to appeal to anyone but the rich and adventurous. High cost‚ fear of flying and the absence of toilets in early airliners (an unfortunate combination) were the main deterrents; the unpressurized aircraft of the inter-war years were noisy‚ slow and not especially comfortable

ABSTRACT Camless internal combustion engines offer major improvements over traditional engines in terms of efficiency‚ maximum torque and power‚ pollutant emissions. Electromechanical valve actuators are very promising in this context‚ but still present significant control problems. Low valve seating velocity‚ small transition time for valve opening and closing‚ unavailability of position sensor are the main objectives to be considered in the design of the valve control system. Actuator physical
