Extraordinary HD-1, or "Krypton" on steroids. Who do we need to learn from?
In Mikhail Zherdev's photo-compilation, published by the Center for Analysis of Strategies and Technologies (Center AST) BMPD 5 in November 2018, we see a far from conventional tactical cruise missile or ballistic missile equipped with a two-stage rocket or solid propellant rocket ramjet engine, solid propellant accelerating engine in the combustion chamber of the IRPD and solid propellant starting accelerator. The engine of the starting stage and the additional upper stage engine, whose fuel charges burn out in about 7 — 10 s, give the HD-1 rocket speed in 1900 — 2200 km / h, and also bring it to the more rarefied layers of the troposphere (to a height of 4 — 7 km) . Thanks to this, the launch and stable operation of the integral rocket-ramjet engine become possible, and the consumption of its solid-fuel gas generator is noticeably reduced, which ultimately significantly increases the range of the tactical missile.
According to informed Chinese sources in October, the successful HD-1 fire tests have already been completed, and the product from the young private company Guangdong Hongda Blasting Company was attracted to the delegation of the Pakistan Defense Ministry. Such keen interest of Pakistani military specialists to the new "straight-through" rocket is explained not only by the traditional dependence of Islamabad on modern Chinese military technologies against the background of the ongoing territorial dispute with Delhi regarding the state of Jammu and Kashmir, but also by excellent HD-1 flight parameters, which are disclosed GHBC headquarters has no plans. Nevertheless, based on direct-flow missile projects such as the X-31A / AD anti-ship missiles (according to AS-17 “Kripton” NATO codification), the Indian XD-SAM / SFDR anti-aircraft missile from DRDO, the Chinese long-range air combat missile PL -15, European Meteor URVB and Japanese XASM-3 anti-ship missiles, it is easy to conclude that HD-1 will have high-speed and maneuverable qualities that meet or even exceed BrahMos multi-purpose tactical missiles based on our 3XXNX anti-ship missiles. Onyx".
While the BrahMosa and Onyxes, equipped with one nose air intake with a central body (“conical flow”), have a marching speed of the order of 2700 — 3100 km / h (at high altitudes), the missiles, whose ramjet inlet devices are represented by two or with four rectangular side air intakes of the so-called “two-dimensional flow” (internal compression), often allowing rockets to realize speed in 3,5 — 4,5М. This feature can be traced when comparing the layout of the input devices of a ramjet ramjet "BrahMos" and the Japanese HASM-3: the latter, equipped with two rectangular air inlets, has a speed of up to 3600 km / h. The Chinese HD-1 has a two-dimensional 4 rectangular air intake, which, with a fairly small mid-section, will provide it with speed within 4-4,5М at high altitudes and 3 — 2,5М at medium and low altitudes. As you can see, the speed capabilities of this product are uncommon, and this fact alone puts it on a level higher than, for example, the American AGM-88E AARGM anti-radar / multipurpose rocket, or our X-XNUMUSHK, equipped with standard solid-propellant rocket engines, after “ burnout ”of which the flight speed is reduced to 58 — 2,5, not allowing to make anti-aircraft maneuvers.
Moreover, the impressive elongation of the housing allows you to place in the internal volume of the HD-1 more and specialized valve regulating the flow of the gas generator to the combustion chamber IRPD. With this device, the gas generator is saved on the main part of the trajectory while maintaining speed at the level of 2,0 — 2,5M, which allows it to accelerate to 3500 km / h at the moment of diving to the target. The work of the IRPD on the final leg of the flight ensures the implementation of intensive anti-missile maneuvers with overloading in 25 — 30G. Today, none of the missiles equipped with a solid propellant rocket motor (except for the Iskander-M 9М723-1) have such qualities. As for the HD-1 guidance system, here we are talking about a multi-frequency active-passive radar seeker designed to “capture” both surface and ground radio-emitting and radio-contrast targets of the enemy. It is integrated with a GPS module and an inertial navigation system. Consequently, to suppress its guidance regimes, it will be necessary to use the most complex spectrum of electronic countermeasures. Export deliveries of HD-1 of the Pakistani army, as well as the Armed Forces of the States of Asia Minor, are able to completely change the balance of forces in several regions at once.
