| Abstract: |
An aircraft having a generally circular or disc planform configuration provides the capability of vertical flight through two concentric sets of lifting fans or blades. The two sets may each include a number of individual rings of blades, but both sets are equal in area and rotate oppositely in order to provide nearly equal volumes of airflow, and thus essentially offset any torque reaction due to the rotation of the blade sets. Several engines are provided in the preferred embodiment, with one engine providing power to the lift fan sets and other engines providing thrust for horizontal flight. Other novel features are also disclosed, such as a peripheral aerodynamic control system, power transmission system, and surface vane system. An alternate embodiment includes a peripheral passenger or cargo area, with more conventional rearwardly located aerodynamic controls for horizontal flight.

First Claim:
Show all 15 claims |
I claim:
1. A disc planform aircraft having vertical flight capability,
- said aircraft having a plurality of concentric lifting fan blade sets positioned around a central cabin area and an upper and a lower surface respectively containing upper and lower lifting fans,
- said fan blade sets comprising a first set and a second set,
- said first fan blade set comprises upper and lower inner lift fans and upper and lower outer lift fans and said second fan blade set comprises an upper and lower central lift fan,
- said first set and said second set having equal projected horizontal areas and rotating in opposite directions to one another,
- at least one engine providing power for said aircraft,
- at least one of said at least one engine providing power for the operation of said fan blade sets, and
- means providing power transmission from said at least one of said at least one engine to said fan blade sets.
