Oct. 23, 2018, © Leeham News: Boeing has been confident it has bottomed out the production rate of the 777 line, successfully bridging between the Classic and the X models.
CEO Dennis Muilenburg nevertheless typically couches this confidence with “with still have some work to do.”
But during LNC’s trip last week to New York, sources said this bridge may be moving to the right.

October 18, 2018, © Leeham News.: Last week we started an article series which analyzes how useful a Boeing NMA will be for medium to long-haul flights in different markets.
We first went through all the factors which will change the OEM’s nominal range to an operational range. Now we fly the NMA in one of its main markets and look how it fairs.

Oct. 16, 2018, © Leeham News: Puget Sound-area Boeing suppliers are anxiously awaiting an Oct. 30th meeting at the Lynnwood Convention Center. The aerospace giant has invited dozens of suppliers to the meeting.
Attendees have been required to sign non-disclosure forms in advance, though Boeing has been tight-lipped about what exactly it plans to discuss with them. Each company has been limited to sending only two representatives, according to several suppliers attending the meeting.
“It doesn’t matter if you’re a machine shop or a big (tier one supplier), you can only send two people,” said an executive at a Puget Sound-area supplier. The supplier spoke on condition of not being named for fear of losing business with Boeing.
Boeing has indicated that the conference is to discuss sweeping changes to how the terms and structure of its supply chain contracts. But it has revealed few details, according to executives at two suppliers.
“You know it’s bad if they won’t tell you what it’s about,” one of the executives said.

Oct. 15, 2018, © Leeham News: Battery technology today leaves a lot to be desired. The energy density of even the most advanced batteries are a sliver of the density in good, old jet fuel.
But batteries pack enough power to lift Zunum Aero’s business plan to develop a gas-electric hybrid airplane. The startup company is convinced battery technology will improve fast enough in coming decades to ensure its airplanes will just keep getting more competitive.
“We come up with an airplane that is pretty good now, and fantastic in 10 years, and just keeps getting better after that,” Zunum co-founder and CTO Matt Knapp told LNC.

This was the leading message from the 5th Annual South Carolina Aerospace Conference and Expo, held Tuesday and Wednesday last week in Columbia (SC).
Conference officials also said they are “exploring a national aerospace coalition.”

The South Carolina Council on Competitive/SC Aerospace already have a Letter of Intent with Washington State’s Aerospace Futures Alliance “for the purpose of advancing the aerospace industry across the US. The LOI will serve as the platform for exploring the creation of a national aerospace Coalition (Coalition) with the objective of strengthening and growing commercial aviation, space, and unmanned aerial systems in the US through a variety of activities.”
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 engines.
We start this week by looking at some design constraints for the engine which we don’t have in Subsonic airliner engines.

This article has been updated to correct an error that misstated the relative size of New Glenn’s payload.
October 11, 2018, © Leeham News: Wednesday’s announcement that the U.S. Air Force had selected Blue Origin along with Northrop Grumman and United Launch Alliance to develop launch system prototypes was welcomed news for the Jeff Bezos-backed company. The Air Force has committed about $500 million through 2024 for Blue Origin’s contract to develop its New Glenn rocket, which will be able to haul 50-ton payloads to low Earth orbit and 13-ton loads to geosynchronous orbit.
Nonetheless, the company’s “entire fundamental business model is based around commercial launches,” Blue Origin CEO Bob Smith said at the Aerospace Futures Alliance’s annual summit in Lynnwood, WA.
Smith said New Glenn is expected to launch in 2021. As recently as this summer, company executives had said first launch is slated for late 2020.
