Compared to classic aerodynamic aircraft, the flying saucer uses thermal energy from the environment. For example, when an aircraft moves behind it, a turbulence zone is formed that can affect other aircraft and is, in fact, the energy of air molecules. The flying saucer uses this energy, which allows you to achieve greater performance with less energy.
In comparison with devices with flapping wings, the simplification of complex oscillatory movements to asymmetric vibration of one plane significantly simplifies the design, increases the resource and allows realizing high power, which is the main problem of the flies. The purposeful use of the thermal energy of the environment makes possible the whole range of maneuvers of birds and insects, which is not available to the existing flies.
Compared to classic balloons and airships, the flying saucer has greater speed and maneuverability. Wind and air resistance, which are a problem for all balloons, are a source of additional power for the flying saucer.
Compared to space rockets, the operation of a flying saucer is much cheaper, since it does not require special launch sites, does not use fossil fuel as a consumable working fluid of a jet engine. In place of it, air is used, and the only energy consumed is electricity.
Unlike existing orbital spacecraft, a flying saucer will be able, with the help of an electric motor, to adjust its orbit for an unlimited time and increase its speed due to a small atmospheric resistance at high altitude, which for conventional vehicles causes a loss of speed and a fall after they use up their fuel supply. necessary to keep the orbit. In addition, the aerodynamic plane, due to its large area and reflectivity, plays the role of a solar sail, which makes it possible to use the solar wind for movement.
Compared to conventional reusable spacecraft, the flying saucer has greater maneuverability at hypersonic speeds when entering the atmosphere and can make a controlled landing without the use of jet fuel and significant restrictions in the choice of time and place of landing.
Unlike a non-powered glider, a non-powered flying saucer can land vertically like a parachute.
