Aerodynamic and Performance Analysis of Ground Spoilers on the Flying V

Optimal design of a lift dumping assembly (LDA) has been found utilizing a gapped spoiler design that consists of two separate surfaces that are placed at 0.06b-0.17b and 0.28b-0.038b spanwise locations. The gapped design allows the cross flow amplified at the hingeline of the inboard spoiler to escape through the middle gap increasing the lift...

Direct statics estimation from ground-roll data

• Statics correction can be computed by inverting the dispersion curves of surface waves (groundroll). • Inversion results generally require intensive processing and are affected by solution nonuniqueness. Here, we directly estimate the statics correction from the dispersion curves of surface waves, without the need for inverting the data. This...
