A tanker is a good fit for a blended wing body. Fuel efficiency is important for that mission, fuel tanks can be easily adapted to the odd shape (compared to cargo), and fuel doesn't care about the bobbing up and down in turns that comes from the wide hull shape (compared to passengers who don't like about that).
Reconnaissance would work too.
- dotancohen 4y ago> fuel doesn't care about the bobbing up and down Maybe the fuel doesn't care, but the flight crew certainly will care about a large oscillating mass constantly changing the aircraft's center of mass.
- pinko 4y agoBaffles are typically used to control this, even in conventional aircraft fuel tanks. It's a non-issue.
- sbierwagen 4y agoI mean, baffles aren't free, since they add empty weight and reduce payload. The designers will be tempted to keep them to a minimum. There definitely will be at least some free surface effect and slosh.
- actionfromafar 4y agoPlastic bags to reduce slosh?
- liotier 4y agoPlastic bags to vomit in.
- somerandomqaguy 4y agoIs it drastically different from conventional aircraft though? The KC-135 houses a great deal of it's own fuel in the wings as well. So does most commercial air liners AFAIK.
- adastra22 4y ago30% more efficient according to the article.
- irjustin 4y agoWonder how much a computer can dampen/remove/counter these sloshing events by constantly adjusting the control surfaces. super interesting stuff.
- 6stringmerc 4y agoWhat about an isolation platform aka a pilot cockpit and boom operator gimble? I agree the computing tech should help a lot! Seeing what experiments were done with the ground effect RC project (what’s his name, cool YouTube vids) indicates the software exists or will soon for a large craft. Especially because this will be generation 3 of a flying wing!
- JumpCrisscross 4y ago> the flight crew certainly will care How long will tankers be crewed?
- nradov 4y agoThe new Navy MQ-25 tanker is uncrewed. I expect this future Air Force tanker will be optionally manned. The main issue is that Air Force tankers use a boom system which requires an operator onboard to manually "fly" the boom into the receptacle. In theory that could be automated but it's a difficult technical problem. Navy tankers use a simpler drogue system which doesn't require a boom operator.
- Jemm 4y agoSurely the fuel will be separated in to multiple tanks with pumps between them, similar to conventional aircraft.
