B2 Bomber. 20 active aircraft currently in service.
Expensive as all crap, but it is effective, had recent upgrades, is capable of using the MOP (Massive Ordinance Penetrator) and do it with stealth.
Yeah, true. The B2 must be considered a flying wing.
The problem is that the Flying wing is a very stable platform.
Well, stable in the roll axis. Not so much in the pitch.
I think another problem is that once you exceed its control limits, stall it or spin it, there is no way out.
Stability, while wonderful for bombers, transport, observation and re-fueling craft is not so great for fighters as they need to walk the fine line between stable and unstable to be able to maneuver quickly. The F-22 in fact is so unstable that it requires computer assistance to maintain level flight.
Basically all types of aircraft except fighters (and, of course, other aerobatic planes) benefit from stability.
I think there are also a number of practical problems with flying wings:
- To have any reasonable payload, it must be rather thick, which either means that it must be very large, or have low top speed. In any case, the flying wing will tend to get a quite low wing-load (wing area/weight), ... which is mainly desirable for fighters
- In mass production, the conventional tube-with-attached-wings layout is extremely practical.
- Tubular fuselages lend themselves nicely to pressurized cabins.
- High-speed, fuel economic designs require high-chord, thin-profile wings, which will leave no space in a flying wing.
... But we are getting off topic.
