Engineering and Assembly Department

Department Overview

The Engineering and Assembly Department is the department of the VHK Tech Innovation Group (VKE Class) that emphasizes practical implementation and engineering realization. As the core carrier that transforms creative concepts into physical objects, it undertakes key tasks such as rocket assembly, equipment development, performance testing, and system integration. With hands-on practice as its core capability, this department uses skilled hands to refine design concepts into operational physical products, serving as the critical bridge connecting the group's innovation achievements from concept to reality.

Core Functions

Rocket System Assembly and Integration

Fully responsible for the assembly work of "VKE No.1" to "VKE No.3" rockets, forming a rigorous assembly process and quality inspection standard:

  • Parts Processing and Preparation: Utilize advanced manufacturing methods such as 3D printing technology, CNC processing equipment, and laser cutting machines to precisely process rocket structural components, connectors, brackets, and other parts, ensuring dimensional accuracy and fit tolerances meet design requirements.
  • Structural Joining and Final Assembly: According to assembly process specifications, sequentially complete the assembly of modules including rocket body structure, engine compartment, payload compartment, recovery systems, etc. Employ various connection methods such as threaded connections, adhesive bonding, and welding to ensure overall structural strength and reliability.
  • System Integration and Commissioning: Integrate and commission subsystems including electronic control systems, sensor modules, communication equipment, and propulsion systems to verify interface compatibility and collaborative working capabilities between systems.
  • Quality Inspection and Acceptance: Establish a multi-level quality inspection system including visual inspection, dimensional measurement, functional testing, vibration testing, etc., ensuring each rocket reaches optimal condition before launch.

Performance Testing and Troubleshooting

Integrate hands-on assembly, performance testing, and troubleshooting to optimize product structure through repeated debugging:

  • Ground Static Testing: Conduct engine ignition tests, control system response tests, sensor data acquisition tests, etc., under ground-fixed conditions to verify performance of each system under real operating conditions.
  • Flight Performance Evaluation: Obtain flight data through actual launches, analyze key indicators such as rocket flight trajectory, velocity changes, and attitude control, evaluate the rationality of design proposals and propose improvement recommendations.
  • Fault Diagnosis and Repair: Establish systematic fault tree analysis methods to quickly identify root causes of problems and develop effective repair solutions. Categorize and organize common faults to form a fault case library and maintenance manual.
  • Reliability Verification: Conduct environmental adaptability tests including high-low temperature cycling, humidity-heat testing, salt spray corrosion, etc., to evaluate rocket working reliability under complex environmental conditions.

Independent R&D of Engineering Equipment

Independently develop multiple types of engineering equipment to meet diverse research and experimental needs:

  • Customized Circuit Board Development: Design and manufacture dedicated circuit boards based on project requirements, including power management boards, signal conditioning boards, motor driver boards, etc., providing hardware support for specific functions.
  • Research UAV Systems: Develop UAV platforms for aerial photography reconnaissance, environmental monitoring, material delivery, and other purposes. Integrate flight control systems, image transmission equipment, and mission payloads to expand the group's aerial operation capabilities.
  • Modified RC Vehicle Models: Conduct secondary development based on commercial remote-controlled vehicle models, equipping them with robotic arms, cameras, sensors, and other devices to transform them into ground mobile robots for site survey, equipment transportation, and other scenarios.
  • Specialized Tools and Fixtures: Design and manufacture auxiliary tools such as rocket assembly fixtures, test benches, transportation packaging boxes, etc., improving work efficiency and operational safety.

Equipment Maintenance and Surface Treatment

Undertake daily maintenance and surface coating work for the "VKE" series rockets:

  • Routine Maintenance: Develop equipment maintenance plans to regularly perform cleaning, lubrication, tightening, replacement of wear parts, and other maintenance tasks on rockets and subsystems, extending equipment service life.
  • Appearance Design and Coating: Design rocket color schemes and patterns based on brand image and aesthetic principles. Employ professional painting processes for surface treatment to enhance product visual texture and recognizability.
  • Protective Coating Application: Apply waterproof, anti-corrosion, wear-resistant, and other functional coatings on rocket surfaces to protect structures from environmental erosion while reducing aerodynamic drag.
  • Label and Nameplate Production: Produce and install team logos, model nameplates, warning labels, etc., perfecting product appearance details and information marking.

Department Characteristics

The Engineering and Assembly Department adopts "Craftsmanship Builds Dreams · Precision Work Creates Excellence" as its philosophy, emphasizing cultivation of members' engineering practice abilities and innovative thinking. The department has established comprehensive project management systems and technical inheritance mechanisms:

  • Standardized Operating Procedures: Compile detailed assembly process cards, inspection specifications, operation manuals, and other documentation to ensure all work follows established procedures and has documented basis.
  • Technical Training System: Regularly organize skills training in mechanical machining, electronic soldering, 3D modeling, etc., enhancing members' comprehensive hands-on capabilities.
  • Project Review and Summary: Organize technical summary meetings after each project completion to share experiences and lessons learned, continuously improving work methods and technical approaches.
  • Cross-Departmental Collaboration Mechanism: Collaborate closely with departments such as Electronics and Information Department and Compounds and Materials Department to jointly tackle technical challenges and achieve complementary advantages.

Team members have achieved excellent results in mechanical design competitions, innovation and entrepreneurship contests, and other activities, with multiple members obtaining patent authorizations. Through participation in real engineering project development, members not only master solid engineering technology but also cultivate rigorous engineering literacy and complex problem-solving capabilities, becoming the backbone force driving the implementation and transformation of the group's innovation achievements.

This department uses exquisite craftsmanship and pragmatic attitudes to transform abstract design proposals into tangible, operational physical products, serving as the practitioner that brings the group's innovation dreams into reality.
