Bjorn’s Corner: New aircraft technologies. Part 18. Minor drags
By Bjorn Fehrm
June 23, 2023, ©. Leeham News: In our series about technologies that influence the efficiency of a new generation of airliners, we have covered the dominant drag of an airliner, air friction drag, and the second largest drag, induced drag, and what can be done about them. Now we look at Pressure drag and Interference drag.
We will finish with Transonic drag next week, which requires a full Corner to explain well.

Paris Day Four: Air show winds down as Spirit strike looms over industry
By Bryan Corliss
June 22, 2023, © Leeham News – The business portion of the Paris Air Show wound down today, with no new orders and news of a looming strike in Kansas that will soon grind Boeing aircraft production to a halt.
It was a stark contrast to the high pre-show expectations. Some analysts were projecting we’d see between 2,000 and 3,000 new aircraft ordered this week in Paris. By our count, there were 1,084 – a sizable haul no doubt. However, 970 of those came from IndiGo and Air India, who had telegraphed their plans to place those orders before the show, and used Le Bourget as a backdrop for signing the papers. Read more
Paris Day Three: Boeing gets small orders; Airbus talks hydrogen and hiring
By Bryan Corliss
June 21, 2023, © Leeham News – After the flurry of news surrounding the blockbuster orders from IndiGo and Air India earlier in the week, Wednesday’s Paris Air Show news was relatively subdued, with Boeing announcing a handful of smaller orders from airlines and leasing companies.
Airbus had announcements of an MOU for a potential widebody order, successful trials of a hydrogen-fuel concept, an update on global hiring – and the winner of a design-the-livery content for its proposed A350F cargo jet.
We’ll need to see a major flurry of orders on Thursday, if we’re to get to the 2,000-plus orders some analysts projected for this year’s air show.
- Indian start up adds 737s
- Air Lease Corp adds 787s
- Airbus halfway to 2023 hiring goal
- First A350F will look like a packing tube
Boeing, GE optimistic for return to normalcy with China

June 20, 2023, © Leeham News: Relations between the US and China remained strained, beginning with the Trump Administration’s trade war initiated in 2017—which continues under the Biden Administration.
The strain has been exacerbated by China’s tilt toward Russia during the Russian-Ukraine war. Except for a brief meeting at this year’s G7 meeting between President Xi and President Biden, there has been little in the way of top-level diplomatic contact until this week. Secretary of State Antony Blinken met with Xi this week, leading to optimism by Boeing and GE Aerospace that relations between the US and China may be thawing.
During executive media briefings surrounding this week’s Paris Air Show, Boeing Commercial Airplanes CEO Stan Deal and GE Aerospace CEO Larry Culp gave their outlooks about the near-term future.
Pontifications: Only time will tell
By Scott Hamilton
June 20, 2023, © Leeham News: Here at the Paris Air Show in what is the first normalized show after the 2020-2021 COVID-19 pandemic, the sense of excitement is almost tangible.
There are predictions by some that when this week is over, more than 2,000 commercial airplane orders could be announced. This would match the heyday of orders in the 2010 decade.
Clearly, there is pent-up demand for new airplanes. Aging aircraft are part of the reason. A push toward more fuel efficient, and therefore more environmentally friendly airplanes is another reason. Full order positions, dating to 2026 for the Boeing 737 and to 2029 for the Airbus A320 is prompting some orders to “get in line.” Even widebody aircraft delivery slots are sold out for the next several years. So is the Airbus A220.
Embraer pulls up the rear with its E-Jet E2. Sales are hampered because the E-Jet family serves a shrinking market, the regional airlines. But Embraer, too, has had a flurry of recent orders.
Airbus and Boeing are talking openly about the next new airplane—Boeing more openly than Airbus. Their confidence is clear.
Alternative energy also takes a front seat at the show. Fuels, batteries, UAMs, eVTOLs, and more vie for attention.
Day One at Paris: Airbus lands record IndiGo deal for 500 A320s
By Bryan Corliss
Monday, June 19, 2023, © Leeham News – Airbus landed a huge but widely expected order for 500 A320s from Indian carrier IndiGo, as the 2023 Paris Air Show got underway Monday.
Analysts had issued pre-show forecasts that orders for as many as 3,000 jets will be announced this week at Le Bourget, as airlines place big bets on a continuing industry recovery from the Covid-19 pandemic worldwide.
Despite the lofty projections, the show got off to a slow start, with only a handful of minor announcements until IndiGo’s big splash late in the Paris afternoon.
- IndiGo has nearly 1,000 Airbus jets on order
- Airbus snags A350 order; could add more
- Boeing announces pilot training deal
- De Havilland Canada plans upgraded Twin Otter
Boeing backtracks on plans to enter 777-300ER P2F Conversions

June 18, 2023, © Leeham News: Boeing shelved its own plans to develop a 777-300ER freighter conversion because the costs didn’t pencil out, the CEO of Boeing Global Services (BGS) said today during a press conference in advance of the Paris Air Show.
Stephanie Pope, the CEO, said BGS, analyzed that a conversion, “but we have licensed Intellectual Property to three providers in the market today. We partner and support that. You’d love to have the economics and we decided that from a capital deployment, it was just not an area that we thought we could invest in deliver the value to our customers. There are other opportunities for us.”
Exclusive: Boeing, GE to send 777-9 to Emirates next year for route proving runs

June 18, 2023, © Leeham News: Boeing and GE Aerospace agreed to send a 777-9 to Dubai next year for about two months of route proving for its largest 777X customer, Emirates Airline.
LNA confirmed the plan on the sidelines of a Boeing event today in conjunction with the Paris Air Show that officially begins tomorrow.
The airline’s president, Tim Clark, has developed a deep skepticism over the pace of the program, which has been hit by repeated delays for a variety of technical and regulatory reasons. The program was launched in 2013, with Lufthansa Airlines, Emirates, Etihad Airways and Qatar Airways as launch customers. Emirates was supposed to receive the first airplane as early as December 2019. Now, Boeing forecasts the first delivery in 2025. Clark is said to be concerned that the delivery will slip to 2026.
Emirates has 115 777Xs on order.
Technical issues with the giant GE9X engine early in the flight testing forced a delay while engines were returned to GE for analysis, fixes and repairs. Then certification work on the program got caught up in the certification crisis of the 737 MAX program following two crashes in October 2018 and March 2019. Global regulators grounded the entire MAX fleet for what became 21 months.
Bjorn’s Corner: New aircraft technologies. Part 17. Airframe with lower induced drag
By Bjorn Fehrm
June 16, 2023, ©. Leeham News: This is a summary of the article Part 17P. Airframe with lower induced drag. The article analyzes Boeing 737 MAX 8-sized airliners with Truss Braced Wings versus wings with folding wingtips and the standard MAX 8 wing. We use our Aircraft Performance and Cost model to get the drag data and overall efficiency improvement for the concepts.
