Abstract
A wingless compact aircraft, with limited footprint and no exposed high-speed moving parts. The aircraft can takeoff and land vertically, can fly at high-speed and even cruise on land and water in one of the preferred embodiments.
Claims13
A vehicle capable of a vertical takeoff and a vertical landing, comprising:
- a body configured to house the elements of the vehicle, the body including a front end and a backend, a profile between a maximum height of the body and the front end having at least a first angled surface and a second angled surface, wherein a first angle of the first angled surface is different than a second angle of the second angled surface;
- a first air flow path extending from an upper surface of the body to a lower surface of the body, wherein the first air flow path extends through the body;
- a first propulsion system positioned along the first air flow path within the body;
- a first set of slots configured to control air flowing through the first air flow path, the first set of slots being positioned through the upper surface of the body, the length of each of the first set of slots being longer than a length of the first propulsion system;
- the first set of slots being positioned at an upward angle from the front end of the body towards the backend of the body and extending across the first angled surface and portions of the second angled surface, wherein a directionality of each of the first sets of slots corresponds to the first angled surface and the second angled surface and is configured to control vertical flow of exhaust air and vertical thrust when the first propulsion system is in a first mode and a horizontal exhaust air flow for horizontal thrust when the first propulsion system is in a second mode;
- a first cavity configured to house the first propulsion system, the first cavity being positioned between the upper surface of the body below the slots and the lower surface of the body, wherein the first propulsion system is configured to rotate its thrust at least ninety degrees around an axle within the cavity, the axle extending along the lateral axis of the vehicle,
- a second air flow path extending from the upper surface of the body to the lower surface of the body, wherein the second air flow path extends through the body, wherein the first air flow path is positioned between a proximal end of the vehicle and a proximal end of a shell, and the second air flow path is positioned between a distal end of the shell and a distal end of the vehicle;
- a second propulsion system positioned along the second air flow path within the body;
- a second set of slots configured to control air flowing through the second air flow path, the second set of slots being positioned through the upper surface of the body, wherein each of the second set of slots is a same length as each of the first set of slots, each of the second set of slots being positioned at a downward angle from the front end of the body towards the backend of the body, wherein the second propulsion system is configured to rotate its thrust at least ninety degrees around an axle while positioned within the cavity, the axle extending along the lateral axis of the vehicle, wherein a rotation of the second propulsion system is contained below the upper surface of the body, and the rotation of the second propulsion system extends beneath a second opening positioned on the lower surface of the body.
