NASA Approves Funding to Develop Zero-Emission Aircraft Prototypes
After partnering with nine academic institutions, Boeing, GE, and the Air Force Research Lab to study the use of liquid hydrogen as an alternative aviation fuel, NASA has given the go-ahead for the second phase, which will involve the construction of various aircraft prototypes. Seen here is a rendering of the final concept called CHEETA, which utilizes a lifting body fuselage to provide sufficient internal volume for the liquid hydrogen and related equipment.

Otto Aviation Concept Jet
Among the various aircraft concepts in various stages of development, one particularly compelling design is from Otto Aviation.
Spiroid Winglets – Sculpting Air to Increase Efficiency
It might not seem logical that adding additional structure to an aircraft’s wing could reduce drag and enable it to slip through the air more efficiently.
Skyryse – Simplifying Aircraft Control with New Technology
Aviation startup Skyryse progresses toward FAA certification for a revolutionary new pilot/aircraft control interface that can simplify piloting and increase safety.
