Barnaby Wainfan
Barnaby is a Technical Fellow for Northrop Grumman’s Advanced Design organization. A private pilot with single-engine and glider ratings, Barnaby has been involved in the design of unconventional airplanes including canards, joined wings, flying wings and some too strange to fall into any known category.
Build, Test, Refine and Fix—Part 6: High AoA Tail Effects
We explore how the tail design can improve pitch stability at high angles of attack.
Build, Test, Refine and Fix—Part 5: High AoA Pitch Characteristics
Evaluating pitch stability, stick force gradients, and pitch-up warnings in stall testing to ensure safe handling at high angles of attack.
Build, Test, Refine and Fix—Part 4: Stall Characteristics
Stall behavior plays a critical role in flight testing. Learn how design tweaks like stall strips and slots improve safety during early flights.
Build, Test, Refine and Fix—Part 3: High-Speed Taxi Testing
High-speed taxi testing requires precise control, detailed planning and cautious execution as speeds approach stall and rotation thresholds.
Build, Test, Refine and Fix—Part 2: Taxi Testing
All aircraft testing, including taxi tests, requires planning and discipline.
Build, Test, Refine and Fix—Part 1: Ground Tests
At some point, a configuration of the airplane is frozen, a prototype is built and testing begins.
Magic Configurations
Designers are continually trying to create new and better machines that will outperform and outsell what is currently available.
Marketability
The manufacturer must be able to sell enough airplanes to stay in business and make some money.
Manufacturing Considerations
The designer must consider all three factors: Mission, Manufacturing and Marketing.
In Case You Missed It
Engine Beat
The Rotax 912 engine has become ubiquitous in homebuilt aviation, and now a company has found a way to improve its fuel efficiency. By Steve Ells.
Fire in the Hole
Were all used to the standard red canister fire extinguisher, often encased behind glass, that we've grown up with at school, work and at home. But the need to put out flames in racecars has brought about a new generation of extinguishers, suitable for aircraft, which offers effective protection in a small and attractive package.
