Simulation test device for water-absorption-and-spraying and fire-extinguishing control system by airplane

Abstract

The invention discloses a simulation test device for a water-absorption-and-spraying and fire-extinguishing control system by an airplane. The device comprises five systems including a comprehensive control system, an airplane task simulation system, a model simulation system, a task scene display system and a signal excitation system. Comprehensive control is in communication connection with flight mission simulation, model simulation, mission scene display and signal excitation to complete control and management functions; Model simulation is in communication connection with comprehensive control, task scene display and signal excitation, completes avionic, electromechanical and water-absorption-and-spraying and fire-extinguishing system model simulation, and dynamically drives the signal excitation system to generate a test signal. By adopting the embodiment of the invention, the problems of dynamic digital simulation and product dynamic comprehensive test for developing the airplane water throwing and drawing fire extinguishing control system can be solved, the development period can be greatly shortened, the development cost can be greatly reduced, meanwhile, multiple rounds of design iteration can be supported, and the maturity and safety of newly-developed products can be improved, so that the development risk can be well controlled.

Description

technical field [0001] The invention relates to the technical field of designing a water-drawing fire-extinguishing aircraft, in particular to a simulation test device for an aircraft water-drawing fire-extinguishing control system. Background technique [0002] With global warming, the situation of forest fires is becoming more and more serious. There are several serious forest fires worldwide every year. Large-scale amphibious and / or seaplane fire fighting has many advantages: it can quickly spread to the center of dense forests that are difficult for people to reach by land. A large amount of water or fire extinguishing agent is put into the fire point, so as to control the fire and establish a control line before the fire spreads in a large area; It only takes tens of seconds to draw water, and only a few seconds to throw water. The single water throw can reach more than a dozen tons, and the single throw water fire fighting area can reach thousands of square meters, so ...

Problems solved by technology

The control of the system involves multiple disciplines such as electronics, hydraulics, structure, and strength. The structure composition principle is relatively complicated, and the ground simulation test is difficult. The existing simulation test technology is only a single supplier to achieve static testing at the component / subsystem level. If the full-function logic dynamic test and abnormal logic dynamic test of the complete mission profile are carried out on the ground, if they are all carried out on the aircraft for flight test, there will be a problem of high flight test cost due to repeated repetitions, and the insufficient ground test will lead to high flight test costs. risk issue
