Configuration Features[9]- Blended wing-body with internal weapons bays

and sufficient internal fuel volume for meeting long endurance mission

- Chinned forebody with radar-compatible nose single piece canopy and good pilot visibility (15 down look over nose)

- Modified diamond wing with a wing span compatible with existing aircraft shelters and constant chord full leading edge flaps aileron and flaperons

- Scarfed wing tip to accommodate installation of various antennas

- All exterior edge angles aligned with either the wing leading or trailing edge angles

21400 Genglin Tang 9

Configuration Features(Conrsquot)[9]

- Twin canted vertical tails constant chord rudders

- All movable clipped diamond horizontal tails

- Two-dimensional convergent-divergent exhaust nozzles with independent throat and exit area actuation and pitch axis thrust vectoring

- Freestream fixed geometry supersonic inlets with sweep cowl lips boundary layer bleed and overboard bypass systems and a relatively long subsonic diffuser having 100 percent line-of-sight RF blockage

- Integrated electronic flightpropulsion control system totally software controlled

21400 Genglin Tang 8

Configuration Features[9]- Blended wing-body with internal weapons bays

and sufficient internal fuel volume for meeting long endurance mission

- Chinned forebody with radar-compatible nose single piece canopy and good pilot visibility (15 down look over nose)

- Modified diamond wing with a wing span compatible with existing aircraft shelters and constant chord full leading edge flaps aileron and flaperons

- Scarfed wing tip to accommodate installation of various antennas

- All exterior edge angles aligned with either the wing leading or trailing edge angles

21400 Genglin Tang 9

Configuration Features(Conrsquot)[9]

- Twin canted vertical tails constant chord rudders

- All movable clipped diamond horizontal tails

- Two-dimensional convergent-divergent exhaust nozzles with independent throat and exit area actuation and pitch axis thrust vectoring

- Freestream fixed geometry supersonic inlets with sweep cowl lips boundary layer bleed and overboard bypass systems and a relatively long subsonic diffuser having 100 percent line-of-sight RF blockage

21400 Genglin Tang 8

Configuration Features[9]- Blended wing-body with internal weapons bays

and sufficient internal fuel volume for meeting long endurance mission

- Chinned forebody with radar-compatible nose single piece canopy and good pilot visibility (15 down look over nose)

- Modified diamond wing with a wing span compatible with existing aircraft shelters and constant chord full leading edge flaps aileron and flaperons

- Scarfed wing tip to accommodate installation of various antennas

- All exterior edge angles aligned with either the wing leading or trailing edge angles

21400 Genglin Tang 9

Configuration Features(Conrsquot)[9]

- Twin canted vertical tails constant chord rudders

- All movable clipped diamond horizontal tails

- Two-dimensional convergent-divergent exhaust nozzles with independent throat and exit area actuation and pitch axis thrust vectoring

- Freestream fixed geometry supersonic inlets with sweep cowl lips boundary layer bleed and overboard bypass systems and a relatively long subsonic diffuser having 100 percent line-of-sight RF blockage

- Integrated electronic flightpropulsion control system totally software controlled
