The SR-71 was a marvel, a super plane that marked an era. The technology it had on it is still unmatched. One of the most impressive things about the jet was its engines. Not only the sheer power of them but their placement of them. Two Pratt & Whitney J58 axial-flow turbojet engines powered the […]
Based on aerodynamics and fuel efficiency design. Nasa and Boeing are studying a concept design named Transonic Truss-Braced Wing (TTBW), belonging to the Subsonic Ultra Green Aircraft Research program. Boeing has a configuration with an outstanding aerodynamic flying within Mach 0.70 – 0.80 (Transonic), a competitive speed similar to airliners. The wing plane comprises a […]
In aviation, coffin corner (or Q corner) refers to the point at which the Flight Boundary is defined by when a high incidence stall intersects with that defined by the critical Mach number. Before we dig further, what is stall and what exactly causes it? STALL Stall is defined as a sudden reduction in the lift generated […]
