Concepts

To gain stealth capabilities, the aircraft is given a design that matches sweeping angles to ``aim the spikes'' and avoids 90 degree corners (which would always reflect a radar beam back to the sender!).

Four main concepts are considered. See sketches in appendix.

1. One engine, low winged, propulsion air intake above wings.
2. Same as 1, but two engines and a slightly different wing configuration.
3. One engine, mid-wing, propulsion air intake below wings.
4. Same as 3, but two engines.
