June 8, 2021, © Leeham News: United Airlines and the start-up company, Boom, last week announced an agreement by which UAL will acquire up to 50 Boom Overture SSTs. There are some conditions Boom must meet before United… Read More
Jan. 28, 2019, © Leeham News: There are too many airliner orders for the future demand, says a leading aviation consultant. No, there aren’t, says the leading industry salesman, now retired. These opposing views emerged at the Airfinance… Read More
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
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
October 26, 2018, ©. Leeham News: In the previous Corner we discussed the noise challenge an SST engine has. To be effective at Supersonic speed it needs a high Specific Thrust (a fast jet out the back) but… Read More
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
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.
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
