Definitions

  • the present invention relates to the field of airships and hot air balloons, both low and high altitude. Specifically, it refers to a controlled system for lifting and vertical landing of said airships and hot air balloons.
  • balonets Currently airships employ for lifting a combination of the power of engines of different kinds and of the difference between the lowest gas density contained in the balonets or a Only balonet and the air that is part of the atmosphere.
  • the gas of the balonets maintains flotation with respect to the weight or 'tare' of the airship while The engines lift the load.
  • This system greatly limits the ability to lifting of the airship with large loads because large motors are needed power to take off vertically. This limitation is compensated by take-offs that are not fully vertical but require long tracks to take off, although shorter than those of airplanes, taking advantage of the lift that produces speed along with the airship surface. Even so, it is very limited since the airship structure does not support large engine powers necessary to lift loads greater than 50 Tm vertically.
  • the present invention relates to a system controlled vertical lift and landing for an airship or balloon aerostatic comprising at least one balonet.
  • the system comprises at least one compressor that removes gas from at least one balonet and compresses it, at least one tank in which the compressed gas is stored, a circuit from at least one balonet up to at least one compressor with a shut-off valve, a connection between at least one compressor and at least one tank and one circuit from at least one tank up to at least one balonet with another shut-off valve and opening.
  • Figure 1 shows a scheme representing the operation of a controlled vertical lift and landing system according to a preferred embodiment of the present invention.
  • the controlled lifting and landing system vertical is based on two fundamental principles of physics, which are on the one hand the Archimedes theorem ('All submerged body in a fluid you experience a vertical and upward thrust equal to the weight of dislodged fluid ') and on the other hand the principle of perfect gases, whose formula is as follows:
  • V is the initial volume
  • T is the initial temperature
  • n are the initial moles of gas
  • the controlled system of the present invention is therefore based on the compression of gas through the use of a compressor attached to a tank that stores the compressed gas and that produces a change substantial between the gas situation inside the balonet and the gas situation inside the compressed gas tank, since the compressed gas will occupy less volume and weigh more, as will be explained later in the present document.
  • FIG. 1 shows a system according to an embodiment preferred of the present invention comprising a balonet 10, which swells or deflation depending on the lifting force needs by means of the gas injection or subtraction thereof, a compressor 12 that removes gas from the balonet 10 and compresses it, a circuit from balonet 10 to compressor 12 and a reservoir 14 in which the compressed gas is stored.
