"Royal Air Hybrid-Multi-Domain Intelligent Tactical Aircraft" is an intelligent manned + military dual-purpose aircraft system independently developed by the Central Plains Institute of Science and Technology team to meet the needs of low-altitude economic development and national defense science and technology. It aims to break the bottleneck of experimental teaching in colleges and universities, fill in the gaps in multi-scenario tactical equipment, and create an innovative solution of "technological breakthrough + integration of production and education + military-civilian coordination. In terms of technical architecture, the project takes "high security, strong adaptation and scalability" as the core to build three core technical systems. At the power level, the oil-electric hybrid architecture and intelligent power distribution algorithm are adopted to realize seamless switching between 120km silent penetration in pure electric mode and 200km tactical maneuver in hybrid mode. It meets GJB 1330A-2004 military fuel standard and can operate stably in extreme environment of -40 ℃ ~ +60 ℃. At the flight control level, it is equipped with military-grade high-precision sensor array and anti-interference adaptive algorithm, build a triple redundant safety architecture with dual redundant flight control computer, four-channel power motor and three-level energy backup, with single point failure degradation operation probability ≤ 0.01, anti-narrow band interference capability up to 60dB, and in line with GJB 2837A-2011 electromagnetic compatibility standard; At the functional level, the design of "hummingbird hydrodynamic chassis" is innovated, and modules such as reconnaissance and surveillance, medical transfer and electronic countermeasure are supported through modular task cabin within 10 minutes to meet the requirements. In terms of application value, the project realizes the three-dimensional coverage of "teaching-military-people's livelihood. In view of the experimental teaching in colleges and universities, breaking through the problems of single function and limited practical operation of traditional UAV equipment, an integrated training scheme including virtual simulation platform and real machine test system has been developed to support the whole process teaching of "theory-simulation-real flight" in courses such as UAV Design and Automatic Control Principles. Joint laboratories have been established with 12 colleges and universities, with an annual training scale of over 2000 person-times. In the military field, the system has passed strict military performance tests and safety certification, and can perform tasks such as plateau border patrols, island and reef supplies, and enemy line infiltration. In the simulation test, the exposure time is 80% shorter than that of traditional landing craft. The field of people's livelihood focuses on emergency rescue and rural revitalization, and the construction of an "air 120" system shortens the response time for emergency and severe treatment in remote areas from 120 minutes to 15 minutes. At present, the project has completed the development of the second-generation prototype and won two computer software copyrights-UAV acquisition data management and control system V1.0, industrial Internet equipment management system V1.0 and general aviation enterprise business license-Civil Aviation Communication (None) Enterprise Zi No. 036759. It has reached strategic cooperation with military enterprises such as China North Industries Group and AVIC, and will continue to promote technological iteration and commercialization in the future, to help China's low-altitude economic industrial upgrading and national defense science and technology independent and controllable development.
