Bjorn’s Corner: Pitch stability, Part 7
Jan. 25, 2019, ©. Leeham News: We have covered the pitch stability for an airliner including some well know problems around deep stall. We now continue with other frequent problems as the aircraft covers a large envelope in speed… Read More
Bjorn’s Corner: Supersonic transport revival, Part 15. Wrap-up.
November 16, 2018, ©. Leeham News: In the last 14 Corners we have discussed the challenges facing the new SuperSonic Transport (SST) projects, 50 years after the Concorde took flight. The challenges facing projects from Aerion Supersonic, Boom… Read More
Bjorn’s Corner: Supersonic transport revival, Part 14
November 9, 2018, ©. Leeham News: In last week’s Corner we compared the GE Affinity, the Mach 1.4 engine for the Arion AS2, to the engine of the Concorde when both propel a Mach 2 Supersonic Transport. We… Read More
Bjorn’s Corner: Supersonic transport revival, Part 13
November 2, 2018, ©. Leeham News: In last week’s Corner we looked deeper into the fundamentals of the Mach 1.4 engine of Aerion’s AS2 SST, the GE Affinity. Now we start looking at engines for a faster SST,… Read More
Bjorn’s Corner: Supersonic transport revival, Part 11
October 19, 2018, ©. Leeham News: In the last Corner we discussed the temperature challenges an SST engine faces. Now we address an even larger problem for SST engines, the takeoff and landing noise.
Bjorn’s Corner: Supersonic transport revival, Part 10
