    Turboshaft and Turboprop Turboshaft and Turboprop Turboshaft and Turboprop I read on your site that a turboshaft uses a series of gear connections to turn a rotor blade. A lot of turboprop engines don't have a direct connection to the propeller but a connecion via a series of...

    Turboprops and Jet Engines Turboprops and Jet Engines Turboprops and Jet Engines I saw a comment on your site saying that the C-130 is powered by jet engines. Correct me if I am wrong, but I flew on a lot of C-130s and none had jet powered engines, they all had propellers. -...

    Getting Started Ok, so we know that we can use a turbocharger to build a jet engine, but how do we go about choosing the right turbo? What sort of thrust levels can we expect? How do I go about designing my combustion...

    Cycle improvements Thermodynamics of a jet engine are modelled approximately by a Brayton Cycle. Increasing the overall pressure ratio of the compression system raises the combustor entry temperature. Therefore, at a fixed fuel flow and airflow, there is an increase in turbine inlet...

    Combustion chamber The burning process in the combustor is significantly different from that in a piston engine. In a piston engine the burning gases are confined to a small volume and, as the fuel burns, the pressure increases dramatically. In a turbojet the air and fuel mixture passes...

    Aircraft Flutter Analysis

    Aircraft Flutter Analysis Flutter can be a problem with any aircraft design and we prefer to predict and modify the critical flutter speed of an aircraft before an incident occurs. We can accurately predict flutter speed with the NISA finite element analysis program...

    Dr. Hans von Ohain and Sir Frank Whittle are recognized as the co-inventors of the jet engine. Each was working separately and knew nothing of the others work. Although Whittle started first, von Ohain was first to design and develop a turbojet engine to power an aircraft. Of the many honors...
