German Secret Weapons of World War II
German jets had many unique designs during World War II. These designs have fascinated many airplane designers since the end of the war. My purpose is not meant to praise the World War II Nazi Air Force, but to show how Germany developed these airplanes and how they used them. It was fortunate for the Allied powers of World War II and the world that the U.SA.F. Defeated the axis powers. If the allies had delayed entering the war a few more months, this would have allowed the Germans enough time to produce large amounts of these jet airplanes, and the outcome would certainly have been different or too close for comfort.

So a jet engine is a machine for turning fuel (Gas&Air) into thrust (forward motion). Thrust produces action-reaction (Newton’s 3rd law of motion). The thrusting action of the exhaust gases produces an equal force in the opposite direction, according Newton's third law, to power the plane forward. The same principal pushes a skateboard forward when you kick backward with your foot. So in a jet engine the exhaust gas from the compressor provides the kick. So let’s look at the engine compressors.
The types of compressors are:
1. Centrifugal flow (whittle engines)
2. Axial flow (Jumo-004 engine)
The engines used by these compressors are:
3. Turbojet engine (Me-262)
4. Pulse jet engine (V-1 bomb)
5. Ram jet engine (various people’s fighter)
During the 1930's two types of compressors were produced, the centrifugal flow or the whittle jet Engine developed by the British and the jumo-004 axial or inline flow. Compressor developed by the Germans. All jets work by exploding a mixture of gases and air inside a turbine to produce power, Allowing for much greater speeds than piston engines. In a jet engine, the compressor pulls in air by rotating and compressing air. The air then goes into a combusting chamber where gas is mixed with it, and burned at high temperatures. The hot gas then travels through a turbine, forcing it to spin very fast. A long shaft connects the two parts together (turbine and compressor), which helps each of the parts to turn more quickly at high speed producing more power, to enable the plane to fly faster than a piston engine.
Another engine was the pulse jet. This was similar to the axial flow jumo-004 engine but with limited fuel and range. It was used in the V-1 bomb
The Ram Jet engine had no moving parts and needed some other types of propulsion to get it up to speed to work. It was used in the German rocket program (ME-163 rocket)
These early jet engines had problems with their rotors, which had to be replaced at about 25 hours of service. This is because if the high temperature of these early engines could not be tolerated by the alloys, the German used for the rotors. This would improve with the next generation of engines. This is important because it allowed only a limited number of fighter jets to be deployed at any given time, which us why only a limited number of planes saw actual combat. Also, Hitler interfered with the development of these new jet engines and threw away the German advantages. He insisted these new planes be used as bombers and not fighters. This was an mistake, because of their sleek design and power plants used. So let’s examine some of the jet airplanes the Germans produced.
Types of aircraft developed using the jet engine
The first jet airplane to fly was the Heinkel-he178, which first flew on august 27, 1939. The man who designed it was Hans Von Ohain who worked for Ernest Heinkel, who specialized I advanced engines. Although Hans Von Ohain of Germany designed the first operational jet...
