Abstract
A boundary layer control arrangement comprises a pulse generator communicating with a surface having a fluid boundary layer thereacross. The boundary layer control arrangement further includes a fluid supply means for supplying a fluid to the surface via the pulse generator. The pulse generator is constructed such that fluid acts on the pulse generator to cause the fluid to pulse. Pulsing fluid passes from the pulse generator to the surface.

A boundary layer control arrangement, comprising:
- a pulse generator communicating with a surface having a fluid boundary layer across the surface, and a fluid supply means for supplying a fluid to the surface via the pulse generator,
- wherein the pulse generator is constructed such that the fluid acts on the pulse generator to cause the fluid to pulse, the action of the fluid on the pulse generator creates the pulses in the fluid and pulsing fluid passes from the pulse generator to the surface.
