In several important previous works [1,2,8-24], each based on the laws of conservation of energy and momentum, the author proposed a new type of rocket engine. The innovated rocket engine extracts energy from the atmosphere as it moves through the atmosphere and uses the harnessed energy to create a powerful propelling thrust. The author shows that if the mass of gas from which the engine is repelled is several times greater than the mass of gas that the engine brakes when receiving energy, then the thrust created by such an engine will be positive. This engine is capable of propelling aircraft to speeds of capable of reaching outer space. In addition, a direct compressor and a motor-generator were invented, in which compression and expansion – the generation of electricity, is produced by an electric field. The author also invented an external rocket-electric motor. All this can make a revolution not only in interplanetary space, but also in future aviation. The cost of fuel is about half the cost of a passenger's ticket in current aviation and almost 90% of the cost of a vehicle-to-space launch. The author uses the word "free" flight or launch in the sense of "without fuel consumption". ---------------------------------------------- Keywords: dipole electric rocket engine.
