Propulsion,Guest Posting on an aircraft, is obtained by creating a force, called thrust, which results from the acceleration of a mass of air by a propeller (driven by a piston engine or a turboshaft engine), or by the combustion of an air/fuel mixture (turbojet engine or rocket engine).

The powertrain, which usually includes one, two or four engines, is one of the main components of the aircraft. This characteristic is often used to classify aircraft: mono, bi or quadrimo, bi or quadritoprop, mono, bi or quadrijet.

The single-flow turbojet engine, which appeared in the Second World War, has given rise to turboprop and turbofan derivatives (turbofan engines) used on almost all heavy or fast-moving aircraft (less than 800 km/h), civilian and military, as well as on fighter jets. There is also a hybrid between these two systems called "propfan".

At the beginning of the 21st century, the propeller-driven piston engine remained the most widely used system in almost all light aircraft (ULMs, planes and light helicopters). It was supplanted by the turbine engine for heavy or rapid helicopters, civil and military. The thrusters are classified below according to their dilution ratio: The proportion between the thrust resulting from the acceleration of cold air and hot air. This classification has the merit of showing that a single principle is used for propulsion, even if it is declined in different technologies. That is why this article includes the propeller-driven motor, the ramjet and the pulsoreactor, which, although they have not undergone significant development, are part of the continuity of the presentation (Petrescu et al., 2017 a-c; Mirsayar et al., 2017).

Speaking about a new engine ionic, means to speak about a new aircraft. The paper presents in a short time the actual engines ion chambers (called the ion thrusters) and other new ionic motors proposed by the authors. The engine (ionic propulsion unit of ions, that real black magick the positive ions through a potential difference) is approximately ten times more efficient than classic system based on combustion. We can further improve the efficiency of the 10-50 times in the case in which is used the pulses of positive ions accelerated in a cyclotron mounted on the ship; efficiency may increase with ease of a thousand times in the case in which the positive ions will be accelerate in a synchrotron high energy, synchrocyclotron or isochronous cyclotron (1-100 GeV). For this, the great classic synchrotron is reduced to a surface-ring (magnetic core). The future (ionic) engine will have a circular particle binding (energy high or very high speed). Thus we can increase the speed and autonomy of the vessel, using a smaller quantity of fuel. It can be used a radiation synchrotron (synchrotron high intensity), with X-ray or gamma radiation. In this case, will result in a beam engine with the wiring (not an ionic engine), which will use only the power (energy, which may be solar energy, nuclear energy, or a combination) and so we will eliminate the fuel. It is suggested to use a powerful LINAC at the outlet of the synchrotron (especially when one accelerates the electron beam) in order not to lose power by photons of the emission premature. With a new ionic engine practically builds a brand new aircraft that can move through the water and air with the same ease. This new aircraft will be able to expedite directly, without an engine with the additional combustion and without the gravity assistance (Petrescu and Petrescu, 2011, 2012, 2013a, 2013b, 2013c).
