U.S. Air Force signs contract to build Quarterhorse hypersonic demonstrator prototype

95

The US Air Force has signed a contract to create a demonstrator of the Quarterhorse hypersonic aircraft, developed by the American company Hermeus Hypersonic. According to Breaking Defense, at the first stage, the military will allocate $ 60 million to developers.

The US military is primarily interested in a combined cycle turbine engine based on the General Electric J85 turbojet engine, which is planned to be used on the demonstrator. Earlier, the company promised to achieve a speed of Mach 5.



Quarterhorse will be the fastest reusable aircraft in the world by the end of the flight test campaign

- stated in the company.

Note that the Hermeus company, created by immigrants from SpaceX and Blue Origin, aims to develop and launch production of hypersonic passenger aircraft. At the same time, she actively cooperates with the US Air Force, which, since 2019, has been financing the company's projects to create hypersonic engines, including for the military. The company has already received an award from the US Department of Defense for developing a prototype hypersonic engine.

As Brigadier General Ryan Britton, who is the executive director of the presidential and executive air travel programs, said last year, "By investing in commercial projects, the US Air Force is bringing new technology to the military."

            The engine in this business is EVERYTHING.

            And if in a combat rocket with an engine it is simpler (it is disposable), then aviation hypersound assumes its reusable, repeated use.
            Therefore, besides all others, there is also a question about the engine resource ...

                      Hypersound is a concept; it has nothing to do with the unit of measurement. Hypersonic speed, this is a speed above 5M, while M (Mach number) is not a constant, but a variable value depending on the speed of sound (M = v / a where v is the speed of an object, a is the speed of sound at a given point in space). The speed of sound decreases with height.
                      If an object moves at a speed of 340 m / s near the ground, then it has 1M, for 10 km at the same speed, the object will have ~ 1,1M

                      Hypersound is possible only in air (the speed of sound in air - that is, at a certain air density, and the air density decreases with altitude on Earth), and the X-15 had a maximum flight altitude of 107 km! ... That is, hypersonic speed, by definition, cannot be achieved in space, but in space, due to the lack of air resistance, much higher speeds can be achieved.
                      So our opponents trump that they easily reach cosmic speeds (in a cosmic vacuum), they say, and then hypersound is not a problem))))
                      And this is actually the mistake of a dilettante, they say if we developed the first cosmic speed (7 km / s) in space, then we can easily reach it under water too)))

However, they invest in a huge variety of programs, and in any case, they will get a positive result in the framework of the research work done. Here are the complaints about the engine - look at the parameters, but it will pull .... So it will not be this engine that will be installed, but based on, using debugged technologies. But for the Uryaklov, this is a cut))) And they will make and debug, do not hesitate .... They have enough resources, but not enough, they will print .... But what I wrote in the comments - it was cut! Instead of using very modest resources for research and development of technologies, it is precisely the laundering of public money and feeding of their own ....

        The aircraft will be able to carry only 19 passengers on board and climb to an altitude of about 18 thousand meters.

          With a similar idea, they were definitely worn back in 1992 on the "Sukhoi". I saw the sketch and the timeline of the execution, that is, they hoped to sell this idea to someone and do it for the millennium.

            Do not need . We divide the square by the radius of the bend (loop). This is acceleration.
            Divide by g = 9,8 is overload in units.

            So, for understanding. We increase the speed 10 times - the radius increases 100 times with the same overload.

              Normal overload ny is the ratio of the algebraic sum of the lift force and the vertical component of the thrust force (in the flow coordinate system) to the weight of the aircraft:
              ny = (Y + Py) / G. The estimated normal overload nyp is the largest overload that can be used in flight in compliance with safety conditions.
              If we substitute the available lift coefficient Cyр into the last formula, then the resulting overload will be available. Nyр = Cyр * S * q / G. There is no speed in these formulas, but there is the magnitude of the engine thrust. does not experience any overload at high speed.

                  You do not take into account the amount of thrust of the aircraft engine. Look at the photo of the x-15 pilots in what anti-G suits they are. You cannot reduce the thrust for the scramjet to perform maneuvers.

        Overload does not depend on speed, but on acceleration
        When accelerating, there will be overload and when cornering

        I wonder what kind of overload the pilot will experience at a speed of Mach 5, what kind of ejection seat and compensation suit for the pilot is needed?


        Very simple. Divide the speed squared by the bend radius. (and divided by 9.8). This is an overload in units. If the speed was 1M, then for 5M you will have to increase the radius 25 times for the same overloads.
        And the chair - there was an SR-71 disaster at 3M. One died, and the second does not remember how he ended up on a parachute. The seat remained in the cockpit. The pilot was simply thrown out of the plane.

          The approach on the other hand is whether the pilot will be able to adequately respond at speeds of Mach 7 to changes in the operational environment. Evolution has not adapted humans for this.

        Moreover, the overload will not be short-term, but constant.

        belay I didn’t understand something? Did you skip physics lessons at school? fool Overload occurs exclusively at ACCELERATION! When driving at a constant speed, there are NO overloads, from the word AT ALL!
        Learn physics (section "Mechanics" (Newton), subsection "Motion of bodies"). And you will be happy!

          You are wrong. It is in the normal straight flight and is equal to one. laughing
          So Newton is certainly right. But this is how it is considered in aviation. There is no overload (equal to 0) only for falling bricks, and from space without air. But in an airplane it will be equal to zero just during a curvilinear movement along a loop, when weightlessness is simulated for astronauts.

              In the United States, the same Aegis system of satellites with IR cameras for tracking ICBM launches and transatmospheric interceptors is already being implemented - all this came from the SDI of the 80s from 1983 to 1994 spent more than 100 billion dollars on research and development on the so-called beam weapons, the implementation was indicated in the mid-20s years of the next century. And now it will not be difficult to put atmospheric interceptors on satellites located on LEO and GPO to begin mass production of the same X 37 and equip them with the same mini interceptors there are no technical problems - there is only money.

        What does it mean they cannot do it - they have already done it and are conducting tests where it does not work, but the fact that they will modify it and eliminate the shortcomings will definitely be. You might think that all our new missiles fly right the first time. And the fact that they will make a hypersonic passenger aircraft over time and with the availability of the necessary funding is beyond doubt.

      if I understand the title correctly, then they will first create a prototype of the demonstrator.
      then, having digested 60 million dollars, they will begin to work on a demonstrator of the model of the pepelats.
