Patent ID: 8474746

Claim:
An aircraft configured for vertically ascending and landing, comprising: at least two wings for generating upward force during forward movement; a space for generating lifting power that contributes to an overall climbing power of the aircraft, the space being provided with a quantity of lifting power units, each lifting power unit comprising a first variable volume for the storage of an amount of relatively light gas which is lighter than atmospheric air, each lifting power unit being configured for the controllable adjustment of the lifting power by means of the first variable volume taken up by the amount of relatively light gas, a gastight total volume in which the first variable volume and a second variable volume are received, the second variable volume being configured for the storage of an amount of gas which is heavier than the relatively light gas, each lifting power unit being configured for the adjustment of a ratio between the first variable volume and the second variable volume within the gastight total volume, the ratio corresponding to a desired lifting power, a flexible wall separating the first variable volume from the second variable volume a first pump configured for the adjustment of the first variable volume, a second pump configured for the adjustment of the second variable volume, a storage vessel configured for the storage of the relatively light gas on expulsion thereof from the first variable volume, a lifting power controller connected to the first pump and the second pump for the controlling of one or more of the first and second pumps in order to adapt the first variable volume or the second variable volume respectively, the lifting power controller being connected to an on-board computer, the lifting power controller being configured for the receiving from the onboard computer of a lifting power control signal for the adjustment of the desired lifting power, the on-board computer being connected to at least one of a position sensor configured for the generating of a position signal for a position of the aircraft, a meteo sensor configured for the generating of a weather condition signal and a load sensor configured for the generating of a load signal of the construction of the aircraft by a load, the on-board computer configured for the receiving of sensor signals from the at least one sensor, the on-board computer being configured to determine, on the basis of the one or more sensor signals, trimming data for the purposes of trimming of the aircraft, the on-board computer being configured to regulate the trimming dynamically based on the upward force generated by the at least two wings contributing to the climbing power of the aircraft; and an intermediate portion provided with thrust motors.
