I. New Breakthroughs in Industry-University-Research Integration: Project Background and Strategic Intent

In response to the policy orientation of a certain province on strengthening the support capacity of scientific and technological innovation, a certain university in North China, relying on the construction project of the experimental platform for fixed-volume bombs used in aviation piston engines, has joined hands with Dianshi Instruments to jointly create a combustion characteristic research system of advanced level. 

The implementation of this project will effectively support the innovative research and development of unmanned aerial vehicle (UAV) power systems and hydrogen energy technologies, providing important technical support for breakthroughs in core technologies in the low-altitude economy and new energy fields.

V. Prospects for Future Cooperation

This cooperation marks a new breakthrough for Dianshi Instruments in the field of non-standard experimental equipment. The successful implementation of this project not only provides hardware support for the discipline construction of the cooperating universities, but also explores a new model of industry-university-research cooperation featuring "universities setting questions - enterprises solving them - joint research and development".

With the official launch of high-temperature constant-volume bombs, it is expected that the cooperating universities will produce influential scientific research achievements in the future, accelerate the incubation of industrialization projects, and inject new impetus into regional economic development.

Vi. Activity Focus: The Industry-University-Research Cooperation Plan for Dingrong Ammunition

Focus on two specialized services to facilitate the efficient advancement of scientific research

In response to the urgent demand of universities and research institutions for high-temperature and high-pressure experiments, Dianshi Instruments has officially launched a dual-track service plan of "trial use of Constant Volume Bomb Products" and "Sample delivery and testing on behalf of others", providing professional technical teams and high-precision equipment to safeguard your research projects.

Activity 1: Trial use of spherical constant volume projectiles

● In-depth Experience: Open 1 set of spherical volumetric bomb flagship equipment (including intelligent temperature control system and data acquisition module), and you can make an appointment for a trial.

● Priority Benefits: If the trial unit makes subsequent purchases, it can enjoy special research subsidies (limited to the first order).

● Worry-free package: We offer technical guidance, operation and maintenance support, and consultation on experimental plans.

Activity 2: Sample Sending and testing service

● Prompt response: Start the test within 3 days after receiving the sample;

● Multi-dimensional characterization: It is used for research on laminar flow combustion, one-time combustion, continuous combustion, etc.
