1969 年,人类登上了月球,也第一次驾驶客机突破了音障。半个多世纪过去,这两件事反而都做不到了。这是 Boom Supersonic(一家做超音速客机的初创公司)创始人兼 CEO 布莱克·肖尔(Blake Scholl)登上 All-In 舞台时的开场白。这期是现场访谈,杰森·卡拉卡尼斯(Jason Calacanis)主持,后半段弗里德伯格和查马斯也加入提问。

公司的旗舰客机「Overture」设计巡航速度 1.7 马赫,已经拿到主要航空公司的 130 架订单。肖尔对波音的评价毫不客气:

波音已经 20 年没造过新飞机了。这是大卫对歌利亚,只不过歌利亚在睡觉。(布莱克·肖尔)

音爆问题怎么解:让它在天上拐个弯

超音速客机商业化的最大障碍是音爆。1973 年,美国立法禁止民用飞机在陆地上空超音速飞行,因为音爆会像爆炸一样打扰地面居民。这个禁令卡了行业 50 年。

Boom 的解法出乎意料地简单,他们叫它「无声巡航」(boomless cruise),学术界的说法是「马赫截断」(Mach cutoff)。原理是利用大气的天然折射能力,让音爆向上拐弯:音爆从飞机上发出后,在空中掉头向上,永远碰不到地面。用肖尔的话说,就像森林里一棵树倒了,但没人在场听见,它算不算发出过声音?

这个技术有个物理上限:大约 1.3 马赫,也就是比今天亚音速客机快 50%。陆地上空不能全速飞,但已经够用了:早上 9 点从纽约出发,9 点半左右就能落地旧金山(跨越时区,实际飞行约 3 小时多)。海上则可以全速 1.7 马赫,反正没人听得见音爆。

更关键的是政策进展。突破音障后不久,肖尔和总统谈过这件事,对方同意「没有音爆,就不该有超音速禁令」。1973 年的禁令在去年 6 月 6 日由行政命令终结,但行政命令理论上可以被撤销,所以他们又去推动国会立法。《超音速合法化法案》在众议院表决,结果是全票通过,随后又全票通过了参议院商务委员会,只差参议院全院表决。

差点死于外包:自己造发动机,涡轮叶片都不放过

剧情在这之后有个急转弯。就在不久前,很多人宣布这家公司已经死了。原因出在发动机:肖尔承认,把发动机开发外包给一家大公司,是他做过最蠢的决定之一。合作方是罗尔斯·罗伊斯(Rolls-Royce),双方高调分手,外界一致认为 Boom 完蛋了。

于是他们决定做所有人认为不可能的事:从零开始自研发动机。而且做得比谁都彻底,用世界最先进的数字化设计工具重新发明发动机的设计流程,再用数字化制造改变生产方式。不只是设计发动机、组装发动机,连涡轮叶片这种最难的零件都自己做。肖尔现场还从口袋里掏出一块涡轮叶片,开了个玩笑。公司理念是工程和制造必须一体化:如果美国要再工业化,就得在这里发明下一代制造技术,用它造出最惊艳的新产品,而不是单纯把丢给中国的产能搬回来。

目前他们第一台垂直整合的发动机核心机正在组装,下个月上试车台。整架演示飞机 XB1 基本上是 50 个人造出来的。

意外的商业闭环:超音速发动机先在地上赚钱

历史上最讽刺的一幕在这里出现:当初所有人都说「没有大公司给你造发动机,你们死定了」,这件事反而成了这家初创公司财务上活下来的关键。

逻辑是这样的:他们的超音速发动机本来就按 1.7 马赫、高温环境、全功率长时间运行设计。把它前端的风扇摘掉,尾部接上一台发电机,就变成了一台无需水冷的大功率发电机组。装进几个拖车,就能为数据中心提供 42 兆瓦的「表后」发电(behind-the-meter,即不经过公共电网的自备电源)。肖尔顺带怼了一句:数据中心耗水这个反对理由本来就不成立,但既然能顺手消掉,那就消掉。

需求端的表现超出预期。肖尔说这是他这辈子见过需求最旺盛的生意:

我的收件箱里躺着数十吉瓦的需求。下个月第一台发动机试车之后,我们就把它拍卖掉。(布莱克·肖尔)

他们正在一个保密地点建造「世界最先进的喷气涡轮工厂」,上上周产出了第一批零件。工厂最终目标是每年数吉瓦的产能,未来五年计划为电网新增 10 吉瓦以上。这套打法与所有老牌航发公司相反:巨头们大量外包、信奉净资产收益率,把皇冠上的明珠都剥离出去;Boom 则从原材料到叶片再到整机装配和试车,全部自己干。

杰森追问是否有客户,比如马斯克的 Colossus 数据中心。肖尔的回答是「你去问马斯克吧」,杰森当场把这翻译成「那就是有了」。

票价、时间表,和什么叫赢

杰森要一个日期和一个数字,肖尔给了:跨大西洋往返,1.7 马赫,3 个半小时,盈亏平衡票价约 3500 美元(往返,不是单程)。实际售价大概率翻倍或三倍,超出平衡线的部分就是航空公司的利润。

首飞时间,官方目标是四年,大约 2030 年前后。但肖尔加了一句他一路学到的教训:

做神奇的事情时,宁可快,也不要可预测。具体多久我说不准,但我们会以物理上可能的最早日期交付。(布莱克·肖尔)

至于会不会做超音速公务机、和湾流(Gulfstream)和达索猎鹰竞争,肖尔的姿态是:希望公务机厂商自己来做,如果他们不做,那我们就做。

被问到什么叫「赢」时,他讲了个女儿的故事。女儿一岁半就跟他看火箭发射视频,两岁半时他带她放模型火箭,结果火箭飞进三个田地外的树里,女儿很伤心。他花了一会儿才明白原因:孩子以为火箭会飞回发射台回收,因为她这辈子看的全是火箭回收视频。超音速飞行也一样:等某一代人听到「跨美国要六个小时」会反问「那纽约还值得去吗」的时候,才算真的赢了。这需要好几代飞机,但他们不放弃。

这一届政府快得多,但超音速本身不是党派问题

公司成立已经 12 年,经历了多届政府。肖尔强调超音速不是党派议题,法案能在国会全票通过就是证明。但他毫不掩饰对这届政府速度的欣赏:周一飞机突破音障,他发推,马斯克转发;当晚他飞去华盛顿启动立法游说,还没落地就收到了白宫西翼的邀请。周四,他们的飞机模型已经摆进了椭圆形办公室,而且现在还在那儿。从突破音障到行政命令签署,用了 115 天。肖尔觉得这算慢的,换一届政府大概率更慢。

他还谈到一个工程师的用人观,值得单独摘出来:

你一旦成为专家,你满脑子装的都是过去,然后你就完全没用了。勇气不是无所畏惧,是明知恐惧仍然行动。(布莱克·肖尔)

整场访谈的信息量集中在三个判断上:超音速飞行的法律障碍正在被彻底拆除,且是以两党全票的方式;被逼自研发动机的绝境,意外打开了数据中心发电这个现金流生意;这两件事互为支撑,地面发电订单给飞机项目输血,发动机在地面被验证得足够充分后,会成为「史上测试最充分的新喷气发动机」。

  • 关注参议院全院对《超音速合法化法案》的表决节奏,它落地意味着超音速出行赛道的监管风险基本清零,相关供应链(高温合金、涡轮叶片、发电机组装)会先于客机交付产生订单。
  • 如果你在 AI 基础设施领域,把 Boom 的 42 兆瓦拖车式无水冷发电纳入备用电源的评估清单:表后发电绕开电网排队,可能是数据中心扩容速度的胜负手。
  • 创业者可以从这期得到的直接经验:把最核心、最难的那一环外包,省下的钱远抵不上失控和分手的成本;而被逼收回来的能力,往往就是你的第二增长曲线。
  • 给超音速出行做的现实预期:陆地上空约 1.3 马赫、跨洋约 3 个半小时、往返票价数万美元级别、2030 年前后,把这四个数字当成你的判断基准,任何偏离都能帮你快速识别利好或风险。

(00:00:00) Set to fly at Mach 1.7 with 130 orders from major airlines. The founder and CEO of Boom Supersonic. Blake Shaw. Boeing hasn't built a new airplane in 20 years. I mean, it's David and Goliath, but Goliath is, like, asleep. We're here to bring back supersonic passenger travel and ultimately to make the planet dramatically more accessible. This whole airplane was built by essentially 50 people. By 50 people. The moment you become an expert, what you're steeped in is the past, and then you're completely useless. Courage is not being fearless. Courage is acting despite the fear. If there's no boom at all, there's nothing to argue about. The world needs supersonic flight. Passengers deserve it. Please welcome Blake Sholl. Good morning. (00:00:54) Houston, we have a problem. We have a problem. In 1969, we landed on the moon, and we flew an airliner through the sound barrier. Yet more than half a century later, we can't go to the moon, and we can't fly faster than the speed of sound. We have a problem. We have a problem. We have a problem. We have a problem.

We have a problem. We have a problem. We have a problem. We have a problem. We have a problem. We have a problem. We have a problem. We have a problem. We have a problem. We have a problem. We have a problem. We have a problem. We have a problem. We have a problem. We have a problem. We have a problem. We have a problem. We have a problem. I thought that would get old, but it never does. XB1 uses actually a far simpler technique than others have talked about to solve sonic boom. We call it boomless cruise, and it uses the natural refractive power of the atmosphere to redirect the sonic boom upwards. So it's like if a tree falls in a forest, but no one was there to hear it, did it really (00:05:27) make a sound? And we talked to the president shortly after breaking the sound barrier, and he agreed if there's no sonic boom, there should be no ban on supersonic flight. So that ban that started in 1973 actually ended June 6th of last year. But this was just an executive order, and theoretically some idiot could reverse it, right? So we went to Congress and we said you should make that permanent. And the Supersonic Legalization Act passed the House. Anybody guess what the vote was? It's actually unanimous. It's unanimous. And it got out of Senate commerce unanimously recently, and now we have to get through the (00:06:15) rest of the Senate, and I think we should just do it unanimously, right? Because that's bad . So, okay. So it's all full speed ahead, right? And like we get to look forward to supersonic passenger flights soon. But wait, there was actually a problem. Not that long ago people declared boom dead. One of the dumbest things I ever did was try to outsource our engine development to a big old company. And that plan didn't work out, and we broke up with Rolls Royce very publicly, and people said we were doomed. So we decided to do the thing everyone said was really impossible, to make our own engine from scratch to pair perfectly with the airplane. And we had an opportunity not just to build our own jet engine, but to reinvent how engines are designed with the world's most advanced digital design tools. (00:07:01) And then to change how they are actually manufactured, also with the power of digital manufacturing. So we're not just designing our own engines, we're not just making our own engines, we're making our own engine parts down to the turbine blades. I have one of those with me this morning. My girl was like, is that a turbine blade in your pocket? Or are you happy to see me? So, our philosophy is that engineering and manufacturing have to work together. And if we want to re-industrialize America, we need to invent the next generation of manufacturing technology here, and use that to build the most incredible new products, not just try to bring (00:07:46) back what we lost to China. So, as we speak, our first vertically integrated jet engine core is getting assembled, and it's going to be in a test stand next month. So, things are starting to get pretty exciting. Now, in a bizarre twist of history, the thing that everyone said would kill us, that we didn't have a big company making an engine, actually turns out to be the thing that makes a supersonic startup financially viable. It turns out if we take our supersonic engine technology, that's designed to run full duration at high power in a hot environment at Mach 1.7, and we take the fan off the front, and instead we put a generator in the back, it does this. (00:08:33) Right? So, our first application of our engine isn't in the sky, it's actually on the ground for data centers. And we can wrap this up in a couple trailers, and we can deploy 42 megawatts for behind-the-meter power generation with a supersonic engine core that's designed to run hot so it doesn't need any water. And I think we all know the water thing is kind of a bullshit objection, but why not make it go away? So, as we speak, we are building, in an undisclosed location, the world's most advanced jet turbine factory. And our philosophy is the exact opposite of what you find at every legacy big company, with lots of outsourcing and a return on net assets philosophy that makes you spin out (00:09:21) your crown jewels. So, we are manufacturing our own engines at scale, starting from raw materials, then going to the parts, including the most difficult ones like blades and vanes, and then assembling them, and then running on our own test ad. And the factory you are looking at here made its first parts last week, and it will scale to making multiple gigawatts per year. And over the next five years, we aim to add 10 plus gigawatts to the grid. And we are looking forward to flying faster than the speed of sound, twice as fast over water, 50% faster over land, with no sonic boom, and doing it on what will actually be (00:10:10) the most tested new jet engine ever made, thanks to being proven on the ground first. So, there's still many, many hard problems to solve. Success is not guaranteed. But I think there's a lot of reason to be excited for a faster future, more connected world, and American leadership in aviation. Nicely done, Blake. We're going to talk for a sec. Stay here. So, a couple of questions for you. Really, when can we get on that plane? How much will it cost? Two very simple things. I'm looking for a date and a number. A date and a number, right? These are my favorite questions. I'm sure your board asks once in a while. You know, I mean, the thing about faster flight is everybody wants it so long as it's safe, (00:10:56) comfortable, and affordable. And Concord is really like zero out of three. Right. And we should do three out of three. So, I'll give you the numbers. Round trip across the Atlantic at Mach 1.7, three and a half hours. And the break even fare is about $3,500. Each way? Round trip. No. Round trip. That's the break even. Okay. And so, of course, it will probably go for more than that. Yeah, double, triple. But any dollar above that, United's making some good money. Okay, fantastic. And win. Our goal is four years. But I think, you know, I think I've learned along the way is it's more important to be fast than to be predictable. So, how long will it actually take? I can't say with certainty. But we are, we're moving as fast as we can and we'll make sure that it's available at the earliest date that it's physically possible. So, we're looking at potentially 2030, give or take, Blake versus say, Elon timing. (00:11:46) So, when you're doing the impossible magical thing, it can take a little extra. You keep talking about over oceans. But my understanding, you were on This Week in Startups a couple times early on, was that you're making it, that the sonic boom is going to go away and become like a sonic thump or a sonic pow or something. It's going to be like a lot less. It's a sonic nothing actually. So, like literally, so there are two different techniques that people use for boom mitigation. And the one we're using is called, we call it boomless cruise. The nerds call it Mach cutoff. The boom comes off the airplane, it's kind of a normal strength boom. Yeah. And it makes a big U-turn in the sky and never touches the ground. And that works up to about Mach 1.3 or 50% faster than how we can fly today. (00:12:35) So, you can't go full speed boomless. But you can still go fast enough that you can leave New York, say at 9am and land in San Francisco around 9.30am. So, it's still going to be pretty, it's going to be pretty great. And then over water, you can go full speed, but no one's there to hear a boom. I mean, this is the key. I think everybody wants to know the New York to Los Angeles, San Francisco time. How is the data center project going? Do you have customers for this product already? And how many, how much is coming in? Let's talk dollars here because running a build in the Concorde is quite expensive as Mr. Bezos pointed out to you. But this seems like a money printing business. Is it printing money? It's an incredible money printing business. I mean, I've never seen demand like this for anything else in my life. (00:13:21) How many orders? Give us a 10 customers, a hundred? There are tens of gigawatts of demand in my inbox. We're going to run that first engine next month and then we're going to auction it all off. Did you talk to Elon about it? Is he interested for the Colossus? You should ask Elon. Okay, that's a yes. Okay, good enough. Do you ever think that like as a name of a company for an airline, boom might be tempting the fates? I got it. I will have a punch up for you. How about Zoom? You know, no one's ever asked me about this before. No, it's like boom and you're there. It's fun. Okay. And we called the company boom because I thought the sonic boom was never going to be the blocker. And so boom is the company. The airplane is Overture. (00:14:06) We wanted an innovative brand for the company and something for the airplane itself that would have real gravitas. There are some individuals who might look at this and say, any chance at a private aviation option in the 2.0? Is that a good business for you to be in to provide, you know, compete with Gulfstream and Falcon? Well, I hope the private jet guys will make a supersonic jet they should. If they don't, I guess we'll do it. Okay. But let's talk about the future. I mean, I'll tell a story. So my daughter, my youngest daughter, who's four and a half now, when she was 18 months old, we'd watch rocket videos. When she was two and a half, I took her to watch a model Estes rocket. (00:14:53) And I'm just the person I am. So I got the smallest little rocket and I put the big D motor in it. And so that thing goes and it ends up in a tree three fields over. And I thought it was pretty cool, but she was upset. And it took me a moment to realize why she was upset, which is she expected the rocket to come back to the pad. Because I had done nothing but watch rocket landing videos with her, like literally her entire life. And what I realized is for supersonic, there's an analogous thing. We will have one when we've sped up flights for every passenger. From the president on a supersonic Air Force One, to a supersonic private jet, to supersonic commercial flights that are available to every class of passenger. And so when you have to convince kids that it used to take six hours to cross the country and they're like, (00:15:39) What are you talking about, Dad? Like who would even do that? Like New York's not worth it if it takes six hours to get there. That's when we've won. And so that will take many generations of airplanes, but we're not giving up. Final question. The company's now getting close to 10 years. 12 in fact. 12 in fact, yeah. Okay, so very close. You passed it. You've had to work with multiple administrations. It's not a political show most of the time. I mean, when Trump's ratings are high, it's a political show. If they go low, talk a little less about it. But, thank you. Talk about how this administration has this administration compared to the last one in terms of embracing what you're doing. (00:16:26) Because this is pretty exciting that you've been able to make such quick inroads in terms of regulations. And that it's a big issue for your company specifically. Yeah. Well, I think, I mean, first off, I think it's really cool that supersonic flight is not a partisan issue. And that we're able to get stuff through Congress unanimously. That said, I love how fast this administration moves. Like, it was, we broke, literally we broke the sound barrier on Monday. I tweeted about it. Elon reposted my tweet. I flew to DC that night to start the legalization campaign. By the time I landed, I had an invitation to the West Wing. So that's Tuesday. Yeah. By Thursday, our airplane model has made it to the Oval Office. And by the way, it's still there. Yeah. It's like one of the greatest product placements of all time. (00:17:12) Like, there's a supersonic jet model in the Oval Office. Like, I kind of love it. And then it took 115 days to get the executive order signed. To me, that felt slow. But it probably would have taken longer in a different administration. Yeah. I think Biden's going to call you back in about two or three weeks from when you called him eight years ago. Yeah. Sounds fast. It's a Biden joke. All right. Let's give it up for Blake one more time. All right. Great job. Thank you. Thank you. Thank you. Thank you. Thank you. Thank you. Thank you. Thank you. Thank you.
