Hypersonic 'space plane' promises four-hour London to Sydney flights by 2030s

https://edition.cnn.com/travel/artic...scn/index.html

.....

- The UK Space Agency announced Tuesday at the UK Space Conference 2019 that it would be working more closely with the Australian Space Agency in an agreement dubbed a "world-first Space Bridge." — The Synergetic Air-Breathing Rocket Engine (SABRE) engine, from Oxfordshire-based Reaction Engines, looks to be the jewel in the crown of this new enterprise. — This is technology that could definitely deliver that. We're talking the 2030s for operational service, and the work is already very advanced.

- In April 2019, Reaction Engines announced successful tests of a precooler, simulating conditions at Mach 3.3, or more than three times the speed of sound. That's more than 50% faster than the cruising speed of Concorde. — At such high speeds, air flowing through the engine can reach incredibly high temperatures, which can potentially cause damage. A precooler reduces the temperature of gases before they enter the core engine itself. Recent tests prove that the component can cool gases from over 1,000 C to ambient temperature in less than 1/20th of a second.

- It "breathes" air from the atmosphere, allowing greater fuel efficiency and lower weight than existing rocket engines that need to carry their own oxygen supply. "The main thing with Sabre is it's like a hybrid of a rocket engine and an aero engine, so it allows a rocket to breathe air. — Rockets really haven't progressed in 70 years, whereas aero engines have become very efficient, so if you can combine an aero engine and a rocket you can have a very lightweight efficient propulsion system and basically create a space plane.

Concorde successor AS2 takes leap forward with vast new Florida HQ

https://www.cnn.com/travel/article/a...-hq/index.html

.....

- The race is heating up to produce the first supersonic passenger aircraft to enter commercial service in more than 50 years. US planemaker Aerion, whose AS2 jet promises to fly New York to London in 4.5 hours, is building a massive new global headquarters in Florida ahead of production beginning on the supersonic craft in 2023. --- The 8-12 passenger AS2 business jet will travel at Mach 1.4 (more than 1,000 mph), which means it could shave three and a half hours off standard journey times from New York to Cape Town, and more than four hours off trips between JFK and Singapore and JFK and Sydney.

- Aerion has already secured a domestic and international order backlog which now tops $6.5 billion and it plans to deliver 300 aircraft over 10 years of production. The AS2's first flight is slated for 2024 and the company intends to take the plane to market in 2026. The craft has a price tag of $120 million, which the planemaker thinks is a price that people will pay because of the time savings. --- The AS2 is designed to meet Stage 5 Airplane Noise Standards, the most stringent landing and takeoff noise regulations. But perhaps one of the AS2's most innovative features is its "boomless cruise" which allows the plane to fly supersonically over land without the boom striking the ground.

You can not snow ski, see historical buildings, and dine on European prepared meals using Zoom.

8-12 passengers will be difficult for public transport profitability, but since when do billionaires care about private toys being profitable?

Whatever, I forsee a court ordered total asset liquidation in the future for this company regardless of how neat people think it would be to fly oligarch express.

Why do we not use flying saucers instead of planes today?

^ That's all the proof you need that there isn't a captured spaceship sitting in an underground hanger out in area 51, because if there was there's no way that this societies industrial complex would not have capitalized and monetized the technology by now - first with military craft and shortly after as civilian.

Our jet liners still have after 6 decades the same basic form, as this is the most suitable form.
