It can be used in combination with many of the existing techniques for passive and active laminar flow control, but is particularly well-suited for a supersonic natural laminar flow design by virtue of avoiding the space, weight, system complexity, and maintenance penalties associated with suction based laminar flow control.This technique injects precisely defined stationary transient growth disturbances into the free air slipstream over a wing that

This is a non-personal service(s) contract to provide certification, emergency maintenance and repair, and decontamination of biological, chemical, and laminar flow equipment (e.g., cabinets, hoods, and blowers) at the Walter Reed Army Institute of Research (WRAIR). Please read all attachments for information.

Proposed solutions include elastic surfaces, coatings, soluble films, and fluid covers. Each of these approaches had significant drawbacks.Coatings offer an advantage over previous strategies due to ease of application, potentially negligible weight penalty, reduced environmental concerns, better economics, and continual function throughout the flight profile.
