History of Ducted Rocket Development at Bayern-Chemie

Abstract: [] After a very short introduction into the history and the business perimeter of Bayern-Chemie, the paper gives an overview of the development of ducted rocket technology at Bayern-Chemie in Germany during more than 30 years. The paper covers main phases of technology development and highlights important achievements. The paper concentrates on hardware design concepts, selected examples of test results and major technical milestones. Based on the advanced state of technology, a contract was awarded to Bayern-Chemie in 2000 for the development and production of the integrated throttleable ducted rocket motor for the European beyond visual range air to air missile Meteor. This propulsion system provides kinematic superiority of Meteor over all existing aircraft weapons and enables continuous optimization of the intercept trajectory by active thrust control. The paper provides a concept overview and a short status of the development of the Meteor propulsion system [1, 2, 3, 4]. The part of the paper dedicated to Meteor will be restricted to unclassified information.

Fit for mission - design tailoring aspects of throttleable ducted rocket propulsion systems

Abstract: () A series of successful flight tests of Meteor (Fig. 1) with a development standard Boron loaded Throttleable Ducted Rocket (TDR) has demonstrated the capability and maturity of this superior propulsion system. Meteor is the medium to long range air to air missile, selected by six European nations (UK, Fr, It, Sp Swe, GE) for air superiority of their fighter aircraft Gripen, Rafale and EF2000 Typhoon. The paper summarizes the basic function of the TDR, the technical status and the major design drivers. Based on the existing technology from Meteor and multiple additional technology programmes, TDR propulsion systems for alternative missions are outlined with respect to the discussed design driving parameters. The Boron loaded TDR is a most promising candidate for future missile propulsion, providing a superior kinematic performance and mission flexibility.

Active recycling control method of air-to-air missile experiment missile

Abstract: The invention relates to an intiative reclaim control method of the air to air missile experiment missile. The method is added with an intiative reclaim control module and a built-in ballute in the inner of the missile, when the experiment occurs with fault or completes the flying test, the intiative reclaim control module is automatically started.

Dynamic Consistency Test Method for Air-to-Air Missile Simulation Results

Abstract: Dynamic consistency test of simulation results is a hotspot and difficulty in the field of the credibility evaluation about air-to-air missile simulation system, which is also the important guarantee of air-to-air missile test and evaluation, and therefore it is must be tested.

Simulation and efficiency evaluation of laser disturbing infrared guidance missile

Abstract: As the typical representative of photoelectric precision guidance weapons, the infrared homing missiles gains more and more applications in the field of military, resulting in the rapid development of related photoelectric interference technology. How to weaken the attacking effect of enemy′s infrared guidance missile has become an urgent problem in naval wars. In the existing optoelectronic countermeasure technology, the laser weapon with unique performance becomes the most ideal weapon counter to infrared homing missiles. Through analyzing the basic capability of some infrared guidance missile, the mathematical models of its cruise trajectory including the missile′s kinematics model, seeker/ tractor model, guidance processor model and collision detection model and so on were established to evaluate the efficiency of laser disturbing infrared homing missile. Matlab/Simulink software was used to construct the whole simulation model for the missile′ s guidance system.The miss distance was used to evaluate the disturbance′s efficiency. At the same time, the declination of the missile′s hit probability was shown. The simulation results show that the laser can disturb the infrared guidance missile efficiently and it can lead the miss distance to increase greatly. With the disturbing range accretion, the hit probability of missile declines rapidly. The results prove that the choice of disturbing occasion, plays an important role on the disturbing effect.

Tactical DIRCM Jamming Pod - Early Operational Assessment

Abstract: : Infrared-guided surface-to-air missiles (SAMs) and air-to-air missiles (AAMs) continue to pose grave danger to U.S. Navy and Marine Corps aircraft. Current tactics against these threats include the execution of evasive maneuvers and the dispensing of flare countermeasures. Improved self-protection capabilities that are essential to enhance aircraft survivability include: (1) the deployment of passive missile warning technologies capable of providing the earliest detection of the threat missile plume ignition and (2) the development of more effective covert laser-based countermeasure techniques. We describe here the development, fabrication, and testing of an operational prototype pod designed to protect U.S. Navy tactical aircraft against the most advanced infrared (IR) guided missile threats.

Study on lateral jet ignition strategy for blend-control missile based on fuzzy neural network

Abstract: Ignition strategy of lateral jet was the key to air-to-air missile with lateral thrust and aerodynamic blend-control. According to the missile fact, by seeking to regulate engine distribution and make right ignition time and ignition logic, the total output of lateral thrust subsystem could be adjusted in the case of the output of single engine was constant. Thus responding rate of missile overload was quickened at the furthest, maneuverability and hit precision of missile was improved. At the same time, the ignition controller of lateral thrust subsystem was designed based on fuzzy RBF network. We can carry out control without mathematics mode. The validity of controller is proved by the result of simulation.
