Testing for laminar flow on new aircraft

Objective

TELFONA will deliver upstream aerodynamics research that will enable innovative aircraft configuration development leading to a step change in aircraft performance. The project will contribute -to the drive to strengthen the competitiveness of European manufacturing industry -to the need to improve the environmental impact of aircraft with regards to emissions. The major objective of the TELFONA project is the development of the capability to predict the in-flight performance of a future laminar flow aircraft using a combination of wind tunnel tests and CFD calculations. This research responds to an opportunity to design a pro-green aircraft configuration with a wing with a significantly higher aspect ratio and lower sweep than today's standard. This configuration has lower drag and higher lift/drag ratio than today's designs. The reduction in wing sweep opens the opportunity for the wing to be designed for natural laminar flow, introducing a further drag reduction. It is predicted that the combined drag reduction could be 20% leading to large reductions in emissions. The achievement of the objective will give the aircraft manufacturers within TELFONA confidence that the flight performance of such an aircraft can be predicted prior to aircraft project launch. The project objective will be achieved through the evaluation of the flow characteristics of the European Transonic Windtunnel, the development of advanced methods for transition prediction and boundary layer flow modelling and the validation of all new techniques through the design of a high performance wing for a pro-green aircraft configuration. The project consortium consists of 15 organisations from 8 different countries whose researchers have significant experience in the areas of wing design, laminar flow technology and wind tunnel testing. TELFONA is structured into five technical workpackages and a dedicated workpackage for project management and exploitation activities.
