European Stars and Stripes (Newspaper) - January 19, 1945, Darmstadt, Hesse                                How a Jet propulsion plane engine works Jet propulsion is a process of taking in Cool compressing and heating then ejecting it at High in the engine shown air is scooped in through a pair of the Rush of air in flight is enough to push it through guide vanes onto the fan Blades of a com called an impeller by centrifugal the whirling Blades compress the air and throw it into a combustion chamber at an increased the chamber has two the inner cell receives fuel from a nozzle like that in an Oil burning the outer cell is like a sleeve around the smaller and there Are Small holes permitting the air to pass from the outer to the inner these Are necessary because the air reaches temperatures of More than degrees in the combustion hot for the Metal of a rotating air seeping through the Small Cylinder brings the Pesature Down to where it can be handled As it passes at High velocity to the Blades of a Turbine then out through a conical Jet give the plane its propulsive although the air passes first through the compressor it is actually the attached to the same that provides the operating Force of the the hot expanding air hits the Turbine Blades so hard that it turns the making the compressor revolve so rapidly that it is continuously sucking in new since the Turbine cannot Start without air from the combustion Cham it is obvious that some starting mechanism is a Small electric motor powered by a 24volt Battery is it is geared to the single Shaft and turns it Over so fast that within 15 seconds the engine is an overrunning clutch automatically disengages the starter when the engine has reached operating and you can turn off the starting motor and ignition Only one spark plug is even though an engine May have a dozen or More combustion Chambers surrounding the Shaft in radial each chamber is connected to All others by a slim so that it is like lighting an oven in a Gas stove you Light the front and the flame spreads Back of its own actually most Jet engines will have at least two spark purely As a safety fac Tor in Case one misses since there is no continuous there Are no electrical disturbances to radio transmission from a Jet and because there is Only one moving part in the engine in lubrication is no prob you can pick up a ups Oil tank and carry it under one air intake fuel coot air vent t Mon chamber matter of the 59 has such a Long Glide that most pilots overshoot on their first the Jet Job has Good stall you get plenty of she then Falls off straight ahead without yawing off into a and when you do want to she handles like a baby Ive pulled the p59 out of a five turn spin in three quarters of a on accelerated turns youve got to watch your because when youre hitting anything Over 400 mph you climb to four is four times the pull of Gravity at sea level in a you can Only take that a few seconds before you Black although enemy Jet planes Are reported to have flown faster than 500 the top Speed and ceiling of the p59 Are still not re engineers admit that the Jet engines do not reach operating efficiency under 400 and Johnston himself has soared past the old prewar Altitude record of How far he is not permitted to even though the Cabin is pressurized for Altitude above he you take along your oxygen when youre at feet real Altitude your Cabin altimeter will read about feet above the Point where you should Start taking the Jet plane climbs from Earth temperatures into the subzero sub stratosphere at such a Ter starter
