BJÖRN JOHANSSONBackground
> 30 years in the Swedish Airforce as Pilot/Engineer
USAF Test Pilot School Graduate, class 91A
16 Years as Test pilot
Flown Gripen since 1992
Mostly involved in flying qualities, flight control system development and high AoA/Spin testing
First pilot to log >1000 h on Gripen
Chief Engineer with Saab since 2006 responsible for
• Gripen Demo
• Gripen E/F

SWEDISH AIR FORCE REQUIREMENTS, 2020-2040
Compared to Gripen C/D the Next Generation should have:
Extended Range
Increased Weapons payload/hardpoints
Mil-Std 1760E cl. 2 weapon pylon interface
Upgraded sensor suite
Improved Communication and Fighter Link
Improved Electronic Warfare capability
Quick software update capability
Low Life Cycle Cost
Full Interoperability
PAGE 4
WHICH WAY TO GO?
Start a “white paper” project
+ Technically no set limits/constraints
+ The engineers dream
- More expensive
- Extensive testing expected
Modify Gripen
+ Possible to reuse design and parts
+ Less expensive
+ Gained experience can be utilized
- Design is already optimized for it's former purpose
Decision: Go for a modification, name it Gripen E/F

GRIPEN DEMONSTRATOR FINDINGS
Gripen could be modified to meet customer requirements on
• Range
• Payload
• New sensor suite/weapons/electronic countermeasures
Demonstrated possible to install
• Engine with higher thrust
• AESA-radar
• New Avionics system
• More internal fuel
Reduced cost and lead time by 60%
• Thanks to new processes and new supplier strategy
• MBD for airframe design
• MBSE for systems development
Risk reduction for Next Generation development
• Customer requirements could be reached

ENGINEERING CHALLENGES
Designing fighter aircraft
• The fine art of making the right compromises
Pilot Situation Awareness – Information overflowHuman Machine Interface must be optimized
Sensor fusion and Decision Support Spider in the web – reduce pilot workload
Important to work close together with the users
