Russia Wants a Hypersonic Bomber

derekmead writes "Hot on the heels of the U.S. Air Force's most recent failed test of an unmanned hypersonic vehicle, Russia now says it wants to jump into the hypersonic game with a long-range bomber. Will Russia's newest Bear fly at 4,500 miles an hour? The Russian military sure hopes so. 'I think we need to go down the route of hypersonic technology and we are moving in that direction and are not falling behind the Americans,' Russian Deputy Prime Minister Dmitry Rogozin said on Russian television. 'The question is will we copy the Americans' 40-year experience and create a [Northrop] B-2 analog or will we go down a new, ultramodern technology route, looking to the horizon, and create a machine able to penetrate air defenses and carry out a strike on any aggressor.' The Russians want their plane operational by 2020, which doesn't seem particularly realistic — we are talking about five times the speed of sound here, and Russia is just starting engine development. The U.S., meanwhile, has been investing in its Waverider program since 2004, and the last test of the X-51A scramjet-powered missile failed after just 15 seconds."

    Glad someone else is stepping up to the plate. Development on such equipment could easily lead to civilian hypersonic aircraft, getting rid of 15 hour flights to Australia and such. Also sparks research on better ways of space travel, as the scramjet is closer to being space capable than a traditional jet engine.

      I recently read that the Concorde, while taxiing into takeoff position, used as much fuel as a modern airliner uses getting all the way to its destination

      That says more about the reliability of your reading material than the fuel efficiency of the Concorde. It's incorrect by three orders of magnitude.

      A 777 uses ~120000kg of fuel for a transatlantic flight. A Concorde uses ~80000kg for the same flight, and ~200kg to taxi into takeoff position.

      The problem is that engine design improvements for airliners over the past fifty years have been aimed at subsonic flight regimes producing the modern high-ratio bypass turbofans where the core jet turbine only produces 15-20% of the direct thrust and the fan produces most of the "push". Sadly fans don't work in supersonic regimes although if some aerodynamic Einstein ever comes up with a solution then the world will beat a path to her door.

      That restricts supersonic flight to rockets, scramjets etc. and to pure jet engines with variable intake nacelle structures that can slow the incoming air to subsonic speeds so it can be compressed, burned and turned into thrust. The Olympus 593s that powered the Concordes are fifty-year-old designs. Modern engines with similar capabilities are a bit smaller, lighter and more fuel-efficient but they are not even twice as efficient as the originals.

    Except for being the wrong plane for the job.

    It is a surveillance plane, not a bomber and not a fighter.

    It takes pictures and goes fast and there is no room for carrying ordnance. It can't even take off with it's fuel tanks full.

    Given that the ISS is ~360 km from the Earth, and it has a 92 minute orbital period, it seems that bombs could be lifted into space, then launched from there. With sufficient supplies and advanced notice you could get enough stuff in position over the long term and deploy in minutes 4500mph = 2km/s and therefore could be at the surface in 180 seconds (3 minutes) once launched. Then there's the issue of changing orbit, which lets assume takes 1 orbit. So you can stike anywhere in the wold in 95 minutes. Can you fuel, prep and deploy a plane in that time? I think not.

    It can take off with full tanks, it just doesn't because it's single engine performance (needed to be considered incase you lose one on takeoff) is poor - they used to fly with full tanks from Kadena regularly, depending on the mission profile.

    Also, there is plenty of room for weapons bays in the payload bays aft of the cockpit - that's where the YF-12A had its Aim-47A missiles stowed. Yup, there was an interceptor variant of the A-12/SR-71 tested.

    It's still the wrong aircraft for the job, because it's been out of service for nearly two decades, and the jigs and tool sets have been destroyed for nearly twice that long.

    There are other uses to a hypersonic aircraft than simply dodging missiles. The ability to arrive on target in minutes instead of hours, for example. Plus, even if the bomber isn't technically faster than the missile, missiles have limited fuel capacity and require a certain reaction time before they can be fired, so if you can build a bomber fast enough, by the time the missile is fired it can't reach you before it runs out of fuel. This is even more true if you are traveling at extremely high altitudes. If you have a bomber traveling at Mach 5 (1 mile per second, roughly) and a missile traveling at Mach 6 launched at the bomber when it is 20 miles away (easily possible for a high altitude bomber to hit a target that far away), it will take 100 seconds to hit, in which time the missile must travel 120 miles, which is outside the range of, say, a Patriot missile (which travels at Mach 5). And the higher the speed, the more fuel it takes for the same distance. A bomber can afford that. It's a lot harder for a disposable missile to do the same.

    I remember reading that if you where to update the SR71 engines with modern alloys (rememberer that the SR71 is a 1960's era plane) that it was possible for them to reach around the Mach 6 range.. as the limiting factor in the fitted engines was their ability to withstand the heat they produced..

    Now that would be something to see!

    "Early 1990s studies of inlets of this type indicated that newer technology could allow for inlet speeds with a lower limit of Mach 6.[46]"
