What is it about?
This paper analyzed the impact of flow control technologies - Active Separation Flow Control (ASFC) and Hybrid Laminar Flow Control (HLFC) on a transport aircraft, and compared various flow control system architectures and the associated economic benefits and flight performance. A trade-off study is subsequently performed to determine the flow control system architecture with most benefits. Also, the combined application of both these technologies are investigated in this paper for a vertical tail plane of a transport aircraft and the results are promising

Why is it important?
Reducing drag during cruise will help in achieving this goal and the flow control technologies such as Active Separation Flow Control (AFSC) and Hybrid Laminar Flow Control (HLFC) promises drag reduction. The system architecture for HLFC and ASFC systems are different and also the needs and purpose of both the systems are different. Considering the application of these two technologies simultaneously on a vertical tail plane of a transport aircraft, a total drag reduction of 3.01% was estimated, with fuel savings of up to 2.02% for a 3000NM range.
Perspectives
One of the top priorities of aviation industry in the 21st century is to reduce the environmental impact of airplanes and to study its impact on the atmosphere. Drag reduction in aircraft especially during cruise is very important to attain these goals. The technologies investigated in this paper namely Active Separation Flow Control (ASFC) and Hybrid Laminar Flow Control (HLFC) promises potential benefits in this direction. The combined application of both these technologies are investigated in this paper and the results are promising
