Voorbeelden van jet propulsion

• This subject has been carefully and continuously studied ever since jet propulsion became technologically feasible.

• Apart from these economic points, we have made a great advance in jet propulsion.

• A special effort has been made to accelerate development of new types of airframes, aero-engines, electronic equipment and improved methods of jet propulsion.

• Does that apply to jet propulsion in the civil field as well?

• I take it that the jet propulsion engine is about as far advanced as the engines we used in the aeroplanes of the last war.

• We may expect with the development of jet propulsion that these times may be shortened very considerably.

• Have any experiments been carried out to see if jet propulsion can be applied to flying boats, in order to do away with propellers?

• We, in this country, pioneered almost every engineering development the world has seen—steam, gas, electricity, and now jet propulsion.
