Re: Tejas Mk2 Medium Weight Fighter: News & Discussion - 23 February 2019

Carrying fuel inside the wings and fuselage is the best way to carry fuel without incurring a significant drag penalty. I don't see why one would not want to maximize that potential as far as possible. Think of it this way, if your wings are carrying more fuel inside them, you may be able to keep a...

Jay, The outer lip of a DSI intake doesn't move inward commensurate to the width of the spill duct. You see the DSI also spills the boundary layer.
