The global target of the project “BinCola” is the experimental verification of benefits coming along with the replacement of classically designed nacelles and HTP by enhanced components specifically developed for natural laminar flow (NLF) development. To ensure a realistic evaluation and assessment of benefits relevant wind tunnel tests will be performed at flight Mach and Reynolds numbers.
An existing basic model of a business jet configuration will be made available by the Topic Manager and serve as the reference configuration. He is also responsible for the provision of the laminar design of the components to be replaced while their detailed design, manufacturing and assembly are part of this proposal.
Transition monitoring is generally performed at cryogenic conditions by using temperature sensitive paint (TSP). To visualize laminar and turbulent areas a positive or negative temperature step has to be performed in a wind tunnel violating by nature the consistency of all flow parameters. New developments at ETW and DLR offer to overcome this deficit by innovative surface heating concepts which are proposed here for application. This approach will make temperature steps superfluous; hence, allow taking images during continuous incidence polars, the standard testing sequence in ETW
