[QUOTE="Gene2memE, post: 77668892, member: 341130"] Do you have a link for Smith et al 2018 on the cost estimates? Part of my work is aerospace consulting and $2.25 billion per year seems very, very low for a major aircraft engineering programme, particularly for something as novel as that with such limited output. Developing large aircraft is [I]expensive[/I]. Boeing was estimating ~$4 billion [I][B]at the start of the 1990s[/B][/I][B] [/B]just to develop the technologies needed for a blended wing airliner with similar size/weight to a 767 (circa 350,000 pound MTOW). That's ~$10 billion in current dollars. Airbus looked at a blended wing airliner before developing the A380 (I got to spend time with the guy who was in charge of aerodynamics for the programme). They estimated that the development cost of a flying wing design would be somewhere around 50% to 80% more than a traditional tube with wings design. Airbus ended up spending about $12-15 billion on R&D for the A380, and another $8-10 billion on tooling up for production. [/QUOTE]
