I wish they could have discussed power source vibration frequency and amplitude issues in both low/high-speed conditions on the airframe during flight and issues it could have on the expansion/compression of the airframe. That might have taken the conversation too deep, but I brought it up because if it is not considered during development over the lifecycle of an aircraft, it can compound structural costs to repair with no way to fix the issue.

Great interview. Nice to hear directly from Joe. Very interesting that Joe discussed the exit nozzle drag issue on the SR-71's engine, but not the reverse circulation around the outside of the engine at high Mach #'s that NASA discovered in the 1970's- which resulted in an enormous amount of drag that Lockheed never found the source of. This led to the SR-71 needing much more thrust (fuel burn) at high cruise speed than had been anticipated. This design to in practice difference impacted the SR-71's range enormously. Curious to know if maybe I have my information wrong, and maybe it is this exit nozzle issue that NASA discovered???

Also emmisivity is a function of several things including wavelength so something can be close to 1 in the infrared but close to 0 in the visible.

[@joed899]

This was an interesting interview. Something that really resonated with me was the fact they use CFD to a point, and wind tunnels to a point. But they go back to the 50's style of pure math to work things out. Then that triggered memories back to dynamics and one of the guys was really punching out the calculus and numerical analysis to understand what he was doing not just doing it. He knew from day one of engineering that he wanted to build rockets. Somehow he knew exactly what he needed to do when the lecturers constantly said "There's a proof for this and you can work it out if you try hard enough but I'll just give you the equation". I feel now, that the lecturers made a mistake. There's knowing and there's understanding. The difference may be subtle but it's Important. It's the difference between knowing your shit and knowing you're shit.

So interesting the back to basics near hand calculated fluid dynamics. My mom was an engineer at AVRO and the ARROW interceptor was designed using slide rules, giant hand cranked mechanical calculators, tables and graphs they hand drew, hand drawn blueprints and models shot off rockets over Lake Ontario for some high speed data.

This guy is great, I cen see his passion and he explains the ideas so well I feel like I understood most of it

[@TheAnachronist]

Man, you really can see the advantage of the X-15 "just use a rocket engine" approach... Especially given the fact they still have to be tied to aerospace primes to help provide large parts of the jet engine, whereas the launch startups often just make their own engines totally from scratch. I really honestly think a rocketplane could be decently efficient, too, using a skip-glide approach, probably allowing transatlantic flight.

[@ewanlee6337]

The benefits from using rockets would not be worth the extra cost from needing to buy/make oxidiser and then carrying that weight increasing fuel use.

[@TheAnachronist]

Oxidizer is extremely freaking cheap, though. That's a thing a lot of people don't get about rockets: the oxygen is basically free, and the acceleration is high enough that the gravity losses aren't a big deal. When I mean free, I mean like $100, maybe even $50 per *tonne*, compared to like $10,000 per tonne of liquid hydrogen. So even though you need 8 times as much oxygen as hydrogen, the oxygen is basically free.@@ewanlee6337

[@emmanuelben1393]

Great video, I enjoyed every bit of it

[@JulianDanzerHAL9001]

23:00 emissivity and absorptivity are the same but they both, together, vary over the wavelength of light as long as yo uare cold enough htat oyur thermal radaition is mostly infrared you can find a surface that has high emissivity and absorptivity in infrared but high reflectivity in visible light and thus get any color while emitting thermal radiation once you get into a heat range where a major part of your thermal radiation is in the visible range (generally called glowing hot duh) you have to decide/trade off depending on the range of applciations how much absorptivity nad emissivity vs reflectivty you want in the range where the visible and oyur thermal radiation overlap

[@someonespotatohmm9513]

ignoring the misordering of letters, this should be a top comment. For ppl who can't read it, reflectivity (or emissivity) is frequency dependent.

[@tvdhauwe]

Interesting video! I hope they will be successful! In that altitude vs airspeed diagram at the end, are you basically finding the geodesic on the fuel-specific energy surface between the origin and the minimum at the target max airspeed?

[@BlahCraft1]

23:00 I could be wrong, but I think the highly emissive white paints work by being highly emissive in the infrared spectrum, while being highly reflective (i.e. white) in the visible spectrum.
