This is to validate the idea that they can reduce the size of the sonic boom. Designing a transport comes after the technology validation. It does seem tough to make a viable transport if it has to have such a long schnoz, though.

Yes , and hanging more engines on a transport is an aerodynamic game changer. Nobody is going to ride in a single engine transport, even if they could scale such an engine, it wouldn't meet redundancy regs. It's going to have to be a modified version of something like the Concorde, but if that long nose on the X-59 is the enabler, that would present a problem.

I didn't think it was about size....but re-directing the sonic (noise) energy so the amount on the ground was tolerable. Username Protected wrote: I heard it's been given the name Pinocchio.

NASA has been doing the sonic boom mitigation research for a long time. Some of my friends are NASA pilots involved in it, and their stories are really interesting. They use a TG-14 motor glider outfitted with a lot of microphones to aid in the research.
Side note: until just a few years ago, they had a very rare YO-3A that they used as the "quiet" aircraft before the TG-14. The plane was sold in great condition, however the owners that bought it are letting it rot in Concorde, CA. Really said to see such a unique aircraft sit in the elements.

I remember the NASA bird. Pilot told me I was the first controller he'd talked to who know what it was, since I'd read about their use in Vietnam.
