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

October 12, 2018, ©. Leeham News: In the last Corner we discussed the challenges of the nacelle outlet for an SST (SuperSonic Transport). Now we will discuss SST engines and what are the key technical challenges for these… Read More

Bjorn’s Corner: Supersonic transport revival, Part 9

October 5, 2018, ©. Leeham News: In the last Corner we discussed the challenges an efficient inlet poses for an SST (SuperSonic Transport). Now we go to the back of the nacelle and look at the outlet.

Bjorn’s Corner: Supersonic transport revival, Part 8

September 28, 2018, ©. Leeham News: In the last Corner we started looking at the biggest challenge for an SST, the powerplant. We first discussed the most fundamental problem of the engine, the level of Ram drag for… Read More

Bjorn’s Corner: Supersonic transport revival, Part 5

September 7, 2018, ©. Leeham News: In the last Corner we looked at the drag hump which is created by several supersonic effects when an SST (SuperSonic Transport) passes Mach 1. Now we will look at other aerodynamic… Read More

Bjorn’s Corner: Supersonic transport revival, Part 4

August 31, 2018, ©. Leeham News: In the last Corner we discussed supersonic lift wave drag and how suddenly the length aspect ratio is more important than wingspan aspect ratio. Now we talk about the problem of going… Read More

Bjorn’s Corner: Supersonic transport revival, Part 3

August 24, 2018, ©. Leeham News: In the last Corner we discussed how supersonic wave drag can be higher than any other drag for a blunt fuselage trying to fly at supersonic speeds. If we try to fly… Read More
