The major international aerospace exhibition “China International Aviation & Aerospace Exhibition 2018” (“China Airshow 2018”), held from November 6 to 11, 2018 in Zhuhai, China, provided visitors with the opportunity to get acquainted with one of the richest and most intriguing expositions from the conglomerate of defense industry companies. Celestial. In addition to the full-size demonstrator of the promising low-signature attack-reconnaissance unmanned aerial vehicle XY-820, equipped with two internal compartments of high-precision missile and bomb weapons, as well as the concept of a unique operational-tactical missile system WS-600L, capable of striking enemy surface and ground targets, simultaneously forcing Operators of the P-8A "Poseidon" until the last moment think that they are dealing with an HQ-9 or C-400 air defense system, armed with cameras, the guests of the China Airshow 2018 were able to capture the layout of the HD-1 multipurpose tactical missile.
In the photo collection of Mikhail Zherdev, published by the blog of the Center for the Analysis of Strategies and Technologies (AST Center) "BMPD" on November 5, 2018, we are presented not with an ordinary tactical cruise or ballistic missile equipped with a turbojet engine or solid propellant rocket, but a two-stage bicaliber missile with an integral marching missile. a ramjet engine, a solid-propellant booster engine in the combustion chamber of the IRPD and a solid-propellant starting booster. The engine of the starting stage and an additional accelerating engine, the fuel charges of which burn out in about 7-10 s, give the HD-1 rocket a speed of 1900-2200 km / h, and also bring it into the more rarefied layers of the troposphere (to an altitude of 4-7 km) … Thanks to this, it becomes possible to launch and stable operation of an integral rocket-ramjet engine, and also noticeably reduces the consumption of its solid-fuel gas generator, which ultimately significantly increases the range of a tactical missile.
In October, knowledgeable Chinese sources said that successful fire tests of the HD-1 have already been completed, and the product from the young private company Guangdong Hongda Blasting Company has attracted a delegation from the Pakistani defense department. Such a keen interest of Pakistani military experts in the new "ramjet" missile 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 over the ownership of the state of Jammu and Kashmir, but also by the excellent flight technical parameters of the HD-1, which should be disclosed. GHBC headquarters has no plans. Nevertheless, based on such projects of "direct-flow" missiles as the anti-ship Kh-31A / AD (according to the NATO codification AS-17 "Kripton"), the Indian experimental anti-aircraft missile XR-SAM / SFDR from DRDO, the Chinese long-range air combat missile PL -15, the European Meteor missiles and the Japanese XASM-3 anti-ship missiles, it is easy to come to the conclusion that the HD-1 will have speed and maneuverability equal to or even superior to the BrahMos multipurpose tactical missiles designed on the basis of our 3M55 anti-ship missiles. " Onyx".
While "BrahMos" and "Onyxes", equipped with one nose air intake with a central body ("conical current"), have a cruising speed of the order of 2700-3100 km / h (at high altitudes), missiles, ramjet input devices of which are represented by two or four rectangular lateral air intakes of the so-called "two-dimensional flow" (internal compression), often allow missiles to achieve a speed of 3, 5-4, 5M. This feature can be traced when comparing the layout of the input devices of the ramjet rocket "BrahMos" and the Japanese HASM-3: the latter, equipped with two rectangular air intakes, has a speed of up to 3600 km / h. The Chinese HD-1 has 4 rectangular air intakes of two-dimensional flow, which, with a sufficiently small mid-section, will provide it with a speed of 4-4.5M at high altitudes and 3-2.5M at medium and low altitudes. As you can see, the speed capabilities of this product are outstanding, and this fact alone puts it on a level higher than, for example, the American AGM-88E AARGM anti-radar / multipurpose missile, or our Kh-58USHK equipped with standard solid-propellant rocket engines, after “burnout "of which the flight speed is reduced to 2, 5-1, 5, not allowing anti-aircraft maneuvers.
Moreover, the impressive lengthening of the body allows placing in the internal volume of the HD-1 a specialized valve for regulating the supply of the gas generator to the combustion chamber of the IRPD. By means of this device, the gas generator is saved on the cruising section of the trajectory while maintaining the speed at the level of 2.0-2.5M, which allows it to accelerate to 3500 km / h at the time of diving to the target. The operation of the IRPD in the final phase of the flight ensures the implementation of intensive anti-missile maneuvers with an overload of 25-30G. Today not a single rocket equipped with solid propellants possesses such qualities (except for the 9M723-1 Iskander-M). As for the HD-1 guidance system, 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, suppressing its guidance modes will require the use of the most complex range of electronic countermeasures. Export deliveries of HD-1 of the Pakistani army, as well as the armed forces of the states of Western Asia, are capable of finally changing the balance of power in several regions at once.
