   Based at first in Tautz' garage, Delta Specialty Company thrived, first making small tools for home shops and later expanding into light industrial machinery. In 1945, Rockwell Manufacturing Company acquired Delta Machinery and renamed it the Delta Power Tool Division of Rockwell Manufacturing Company and continued to manufacture in Milwaukee.

4. Jet aircraft - Wikipedia

   en.wikipedia.org/wiki/Jet_aircraft

   A jet aircraft (or simply jet) is an aircraft (nearly always a fixed-wing aircraft) propelled by one or more jet engines . Whereas the engines in propeller-powered aircraft generally achieve their maximum efficiency at much lower speeds and altitudes, jet engines achieve maximum efficiency at speeds close to or even well above the speed of ...

5. Components of jet engines - Wikipedia

   en.wikipedia.org/wiki/Components_of_jet_engines

   Components of jet engines. Diagram of a typical gas turbine jet engine. Air is compressed by the compressor blades as it enters the engine, and it is mixed and burned with fuel in the combustion section. The hot exhaust gases provide forward thrust and turn the turbines which drive the compressor blades. 1.

6. Jet engine - Wikipedia

   en.wikipedia.org/wiki/Jet_engine

   Jet engine. A jet engine is a type of reaction engine, discharging a fast-moving jet of heated gas (usually air) that generates thrust by jet propulsion. While this broad definition may include rocket, water jet, and hybrid propulsion, the term jet engine typically refers to an internal combustion air-breathing jet engine such as a turbojet ...

   The first working pulsejet was patented in 1906 by Russian engineer V.V. Karavodin, who completed a working model in 1907. The French inventor Georges Marconnet patented his valveless pulsejet engine in 1908, and Ramon Casanova, in Ripoll, Spain patented a pulsejet in Barcelona in 1917, having constructed one beginning in 1913.

9. Fuel economy in aircraft - Wikipedia

   en.wikipedia.org/wiki/Fuel_economy_in_aircraft

   Fuel economy in aircraft. Between 1950 and 2018, efficiency per passenger grew from 0.4 to 8.2 RPK per kg of CO₂. [1] The fuel economy in aircraft is the measure of the transport energy efficiency of aircraft . Fuel efficiency is increased with better aerodynamics and by reducing weight, and with improved engine brake-specific fuel ...
