The heat accumulating type cooling system comprises a fresh water pipeline anda seawater pipeline which are jointed at a heat exchanger, the fresh water pipeline comprises a fresh water pump, the input end of the fresh water pump is connected with the heat exchanger, and the output end of the fresh water pump is connected back to the fresh water pump through a pipeline after being sequentially connected with heating equipment and a heat storage tank; and a first stop valveand a second stop valve are connected to the pipeline in series, two branches are connected to the pipeline between the two stop valves, one branch is connected to the input end of the heat exchangerand is provided with a third stop valve, and the other branch is connected to the pipeline between the heating equipment and the heat storage box and is provided with a fourth stop valve. Through thearrangement of the heat storage tank and the corresponding stop valve, when the seawater pipeline is disconnected, the heat storage tank can complete cooling of the heating equipment, and then the seawater pipeline is connected to synchronously cool the heat storage tank and the heating equipment; and the heat storage box can also be isolated. The problem that seawater enters a cabin due to largedeepwater pressure is effectively solved, the problem that outboard seawater is heated due to cooling in a special period is effectively solved, the use performance is good, and the practicability ishigh.

Culminated turboshaft engine, turboshaft engine culvert control system and control method
ActiveCN109324528BImprove outlet flow field distributionReduce total pressure lossDispersed particle separationProgramme control in sequence/logic controllersTemperature controlAuto regulation
The invention discloses a culvert type turboshaft engine and a turboshaft engine culvert control system and method. According to the culvert type turboshaft engine, an outer culvert is arranged at theperiphery of a core engine and connected with a bypass flow channel of a particle separator, and thus bypass airflow of the particle separator enters the outer culvert and is utilized to cool a powercompartment and an outer culvert cartridge receiver; according to the turboshaft engine culvert control system, by collecting the temperature of the power compartment, an adjusting mechanism is controlled to adjust the air flow quantity entering the outer culvert and the core engine, thus the temperature of the power compartment is automatically adjusted, the working performance of the engine isimproved, and the working reliability of the engine and accessories is improved; and according to the turboshaft engine culvert control method, the operating environment of a helicopter, the temperature of the power compartment and a weapon launch signal generated by a weapon launch system are synthesized to control the bypass airflow of the particle separator, and thus the functions such as active particle separation, the adjustable temperature of the power compartment and jet nozzle infrared suppression are achieved.

The invention relates to a deformable aircraft, as well as a use field and the application thereof, and provides a structural design scheme, a structural design method and the application of a novel deformable aircraft. According to the scheme and the method, a telescopic mechanism and a rotatable mechanism are spatially arranged and combined; a radar reflector is applied to a mechanism; a fuel gas power device is applied to the mechanism; and a foldable high-temperature-gas-resistant special textile fabric is applied to the mechanism. After the aircraft is unfolded, the aircraft can generate an infrared characteristic and has an appearance characteristic of an aircraft body; the product produces a flight accompanying product with the same size as an aircraft platform, can be used for protecting the platform, and can also be used for specific performance purposes; the method is used for a specific product which needs to simulate the same characteristics of medium and remote monitoring and display of an original aircraft platform. The structural design scheme and the method of the deformable aircraft are mainly applied to all aircraft platforms (including various water surface ships and boats and ground mobile platforms), including unmanned or manned aviation aircrafts, such as transport aircrafts, helicopters, fighters, bombers, aerospace crafts, manned spacecrafts and the like.
