Summary
This paper addresses some realistic requirements for the design of a Hybrid Laminar Flow wing with special attention to the application on production aircraft. After successful wind tunnel and flight tests the capabilities of the HLF technology are proven and the application on a commercial basis is subject of current efforts.
Stability computations with the linear PSE approach of the A320 HLF Fin reveal the aerodynamical drawbacks in test cases with increased stringer width, suction chamber failure and outflow from a suction chamber.
It comes out that within limits concessions to the ease of manufacturing or to other systems for a commercial application might be balanced with higher suction rates and therefore higher power requirements for the HLF system.
