DESC:4. DESCRIPTION
Technical Field of the Invention

This invention relates to the field of defence and technology mainly refers to defence training systems and simulators that blanket real environment scenarios.

Background of the Invention

In the ever-evolving landscape of defense and technology, training systems and simulators play a pivotal role in ensuring the preparedness and efficiency of military personnel. Among the array of weaponry, high-angled firing weapons, particularly the 60mm mortar, hold strategic importance in indirect fire support scenarios. However, the conventional methods of training, which heavily rely on live firing exercises, have encountered challenges that necessitate innovative solutions. The present invention emerges from the recognition of these challenges and a visionary attempt to revolutionize the training paradigm for high-angled firing weapons.

The 60mm mortar, a versatile and widely employed weapon, has traditionally been a mainstay in military training programs. Its ability to provide close fire support with various ammunition makes it an indispensable asset in the defense arsenal. Live firing exercises with the 60mm mortar have historically been instrumental in honing the skills of military personnel, especially Mortar Fire Controllers (MFCs). However, the prohibitive costs associated with live firing, coupled with safety considerations and logistical challenges, have cast a shadow on the efficacy of this traditional training approach.

Moreover, the sporadic nature of live firing exercises and the constraints imposed by weather conditions and ammunition availability have further impeded comprehensive and frequent training sessions. As a result, there arises a crucial need for alternative training methodologies that not only address the financial and logistical barriers but also provide a controlled and structured learning environment.

To bridge the gap between the imperative for effective training and the limitations of live firing exercises, several prior art solutions have been explored. Notable examples include NL2007271C2, US2801586A, EP0952422A1, US6059573A, US4326847A, US20160169626A1, US7421934B1, and US4711180A. These prior arts, while contributing valuable insights and technological elements, exhibit certain limitations.

NL2007271C2, for instance, discloses a mobile mortar simulator system, but its focus remains on tube simulation without encompassing the breadth of training requirements. Similarly, US2801586A introduces a sub-caliber mortar shell, but its scope is limited to the projectile itself. These prior arts offer incremental advancements in specific aspects of simulation but fall short in providing a holistic and integrated solution for high-angled firing weapons.

The simulator systems of US6059573A and US4326847A introduce full-size training devices and launch environment simulation, respectively. However, these systems lack the comprehensive interactive elements necessary for blanketing the dynamic scenarios encountered in real-world military operations. They simulate specific components but do not integrate seamlessly into a structured training program.

While US20160169626A1 and US7421934B1 delve into the simulation of mortar functions, they are primarily centred around the physical aspects of the mortar itself. The lack of integration with instructor consoles and comprehensive display units limits their capacity to deliver a fully interactive and immersive training experience.

US4711180A introduces a method for training with reduced firing distances, but its focus on propelling charges and sub-caliber flight projectiles does not address the broader spectrum of skills needed for Mortar Fire Controllers. These prior arts, collectively, underscore the incremental nature of advancements in simulator technologies for high-angled firing weapons.

In dissecting the limitations of existing solutions, the inventors recognized a glaring gap in the realm of high-angled firing weapon simulators. While prior arts contribute to specific components or functions, none holistically address the multifaceted requirements of training with high-angled firing weapons, specifically the 60mm mortar.

The envisioned solution seeks to transcend the shortcomings of traditional live firing exercises and existing simulator systems by introducing a cutting-edge, computer-generated imagery-based training system. The goal is to create an environment that authentically blankets real-world scenarios, offering a comprehensive and immersive training experience.

The inception of the present invention arises from a dire need to enhance the quality and frequency of training for force readiness, particularly in the context of high-angled firing weapons like the 60mm mortar. The inventors recognized that simulation provides a cost-effective avenue for teaching initial weapon handling skills and addressing training aspects that live firing exercises cannot adequately cover due to safety concerns and logistical constraints.

The prior arts, while commendable in their contributions, lacked a fully interactive, computer-generated imagery-based high-angled weapon simulator system designed to blanket real experiences in a classroom setting. None of the existing solutions comprehensively addressed the challenges faced by Mortar Fire Controllers in target selection, prioritization, and engagement.

a. positioning the 60MM mortar blank with the bottom plate (2), sub plate (3), joining assembly (4), two target adjusting knobs (6, 7), barrel assembly (5) with a sighting subsystem (10), and sensor assembly (20) in a training environment;
b. activating the visual station (8) to generate realistic 3D scenarios for the Fire Control Station (9), projecting onto the screen (12) through the projector (11);
c. utilizing the instructor station (13) with the instructor console (15) to control and oversee exercises, including selecting, creating, initiating, and modifying exercises;
d. interacting with the system through trigger sensors, azimuth sensors (31), and elevation sensors for enhanced control during training exercises;
e. adjusting targets using the target adjusting knobs (6, 7) and securing identified targets with the locking mechanism (7);
f. detaching blank missiles (19) from the barrel assembly (5) by holding the top ring of each provided blank missile;
g. employing the software module to simulate various exercises, including adapting scenarios, generating performance reports, and grading trainee performance.
