“…The suffix "E" (for "intake", in German "Einlauf") was added to indicate that the model contains a modular center body section that can be exchanged with a flow-through inlet section. The effect of the inlet as well as various leading edge shapes have been studied in previous high-speed tests of the DLR F17E [11]- [13].…”

Extensive experimental and numerical investigations on a highly swept generic unmanned combat aerial vehicle (UCAV) configuration of lambda type with a variable leading edge contour have been conducted. Within these investigations it was shown that the flow field is dominated by complex vortex systems including vortex-to-vortex and vortex-to-boundary layer interactions. The vortex dominated flow field has a strong nonlinear influence on the aerodynamic behavior of the configuration. Hence, the controllability aspect is demanding and poses a real challenge in the design of this kind of configuration. Especially the dimensioning of the control surfaces for the lateral-and longitudinal stability aspects of tailless configurations of low aspect ratio and high leading edge sweep poses a challenging task, which is not yet solved.
