    The front inlet is the ramjet inlet, the second is scramjet inlet. They will not be both working at the same time for long. What will happen is you have the rocket booster stage which will accelerate the missile from stand still to a speed where the ramjet will start working, the booster is jettisoned and ramjet kicks in to accelerate the rocket to high supersonic speeds where scramjet will start working. Scramjet will then kicking in and push the speed higher still and the efficiency of ramjet will drop until it ceases to function and you have a hypersonic vessel traveling mainly by scramjet.

    This could allow both longer range and more flexible approach as the missile can fly high in scramjet mode to cover distance quickly and cover more distance at higher speeds, then when dropping low for final approach kick ramjet back in to ensure high speed final run where scramjet won't likely to work because of higher air resistance at near sea level altitude.

    The dimples you see probably correspond to closed ramjet intakes if you try to translate this drawing to CX-1, while the ring opening that you see may be for scramjet.

    Not only are the intakes separate but the combustion chambers for both is also separate. The ramjet combustion chamber is likely to not be working when scramjet flight takes over or at least not contributing to scramjet operation.

    I am skeptical about the ram jet igniting the scam jet since you are blowing in exhaust gas into the combustion chamber filling it with inert gas acting like an extinguisher. If the scram jet doesn't ignite there will be no "ram jet ceases to function" stage.

    Maybe, I don't profess to know the details of ram and scramjet operations. They could shutdown the ramjet first before shortly kick starting the scramjet, as there would be an overlapping speed range where both ramjet and scramjet would operate.

    I guess this kind of design opens up the potential for hypersonic vehicle that is surface launched rather than air launched. The booster stage required to accelerate a vehicle to scramjet operating speed from ground would likely be too large, but they can accelerate it to a speed where ramjet would work first during climbing, then use that to kick into scramjet range at high altitude before switching over to scramjet.

    It's a controllable and guide able flight in 2012 that demonstrated a coaxial inlet scramjet vehicle. At the time of that article's publish they have started working on the wave riding vehicle concept.

    ^^^ I just went to your link and google translated the following from Henri K. This guy seems to posts all sorts of interesting developments regarding China defence history and progress:

    If that scramjet is actually on the CX-1, then there's really no room for a radar.

    For the general AShM mission, I'd rather have a Mach 3.0-3.5 ramjet missile with a radar, than a scramjet Mach 5.0 that has to be datalinked or uses inertial guidance.

    I think CX-1 only has ramjet engine if its top speed is Mach 2.5-3 as advertised, the scramjet translation is likely an error.

    Hi Guys, I don't know if this will bring new details (probably not) but here it is...
    (FYI I am not at Zhuhai, my colleagues specialized in army / land systems are... but they are trying their best to identify new naval products, get information and send everything to me to publish articles).

    There are actually two versions...

    CX-1 wouldn't have been available for export if it had a scramjet.

    Now I realize that the missile tested in 2012 is hypersonic, it reached a speed greater than Mach 5 and an altitude greater than 20,000 meters. So it makes CX-1 looking like a byproduct of China's research on air-breathing hypersonic missile. If that is the case, then CX-1 is just a side show, and therefore it is probably for export only.
