Methods and Apparatus for Robust Lift Generation

摘要

Apparatus and methods for robust lift generation through flow separation suppression are disclosed. One example apparatus includes a cowling extending from a surface of a fluid dynamic body to provide an exhaust stream directed over the fluid dynamic body. The example apparatus also includes a fluid ejection slot proximate or on the fluid dynamic body, where the fluid ejection slot is to direct a compressed fluid along a surface of the fluid dynamic body. The example apparatus also includes rotatable vanes having blunt leading edges, where the vanes are proximate the fluid ejection slot to direct the compressed fluid to affect attachment of the exhaust stream to the fluid dynamic body to enhance lift.

1. An apparatus comprising:
a cowling extending from a surface of a fluid dynamic body to provide an exhaust stream directed over the fluid dynamic body; a fluid ejection slot proximate or on the fluid dynamic body, the fluid ejection slot to direct a compressed fluid along a surface of the fluid dynamic body; and rotatable vanes having blunt leading edges, the vanes proximate the fluid ejection slot to direct the compressed fluid to affect attachment of the exhaust stream to the fluid dynamic body to enhance lift.
