“…A significant amount of modeling and simulation work for ship-helicopter DI has been conducted to improve the understanding of the physical processes taking place at the DI. They are devoted to developing tools for the analysis of the mutual ship-helicopter interactions and Ship Helicopter Operating Limits (SHOL) predictions to support at-sea flight tests [2]. In general, the numerical studies of the ship-helicopter DI mostly do not consider the mutual coupling of the ship and the helicopter.…”

Landing a helicopter to the ship flight deck is most demanding even for the most experienced pilots and modeling and simulation of the ship-helicopter dynamic interface is a substantially challenging technical problem. In this paper, a coupling numerical method was developed to simulate the fully coupled ship-helicopter flow-field under complete wind-over-deck conditions. The steady actuator disk model based on the momentum source approach and the resolved blade method based on the moving overset mesh method were employed to model the rotor. Two different ship-helicopter combinations were studied. The helicopter flight mechanics model was established and then the influences of coupled airwake on the helicopter were analyzed. Finally, based on the derived rejection criterion of safe landing and the developed numerical method, the flight envelopes for these two ship-helicopter combinations were predicted. The steady actuator disk model was found to be effective in the study of helicopter operations in the shipboard environment. The calculated flight envelopes indicate that an appropriate wind direction angle is beneficial to increasing the allowable maximum wind speed and the operating boundary is affected by the rotation direction of the main rotor.

“…The process of producing explosives in a mixer truck realizes an integrated service model for the production, distribution, and blasting of explosives, integrates the upstream and downstream chains, achieves closed-loop management, reduces safety risks, and improves work efficiency [13][14][15]. China's mixed explosives truck production and operation technology has been developed and developed since the 1960s, and the technology was introduced from abroad in the 1980s [16]. After decades of development, the mixed explosives truck production technology has been continuously improved, the performance has been significantly improved, the application range has been continuously expanded, and the integrated service mode of mixed explosives truck production has become mature [17][18][19].…”

To improve mine production efficiency, reduce blasting costs, and meet the needs of mine capacity expansion, the use of an on-site mixing emulsion explosives truck for open pit iron ore deep hole step blasting charging operation. This paper firstly briefly introduces the process flow of emulsion explosives production and makes a detailed introduction to the working principle and process control requirements of each section of emulsion explosives production. Based on the analysis of the basic principle of adaptive control, the adaptive PID controller is designed to control the discharge temperature and density of emulsion explosives production and to achieve self-tuning of parameters, which improves the control accuracy of production parameters and product quality. The research results show that the use of field mixing emulsion explosives, and blasting operations personnel was reduced by 40% to 50%, and the drilling workload was reduced by about 7%. The application of field mixing emulsion technology improves the blasting effect, increases shovel loading efficiency, reduces the labor intensity of workers, saves comprehensive mining costs, and reduces the cost of temporary explosives depot guarding and disposal of used packaging in mines.
