Problems solved by technology

[0004] The technical content of the present invention is: use aluminum film to vacuum-encapsulate the metal powder to make it a standardized metal powder basic unit, weld the aluminum film packaging interface to isolate the metal powder from the external oxidant, and make the metal powder The basic unit is bonded into a standardized grain, and then the grain is packaged in a joint-shaped standardized package. The polymer film used in the joint-shaped package is resistant to salt spray and seawater erosion, which solves the problems of storage, transportation and use of metal powder in the past. many problems; the jointed powder column is convenient to realize the automatic filling of metal powder into the engine combustion chamber. The invention proposes a feeding method that uses the ejector pin to feed the combustion chamber. The powder column is broken under the action of the high-speed rotating turbine. The high-speed rotating turbine has a shearing effect on the metal particles and the packaging aluminum film, and makes the metal particles scrape each other, destroying the oxide film on the surface of the metal particles, making the metal particles It reacts with the water injected into the combustion chamber to generate heat and generate metal oxides and hydrogen; the metal oxides, hydrogen and incompletely burned metal particles generated in the combustion chamber travel to the supplementary combustion chamber, where they are combined with the intake air Oxygen in the air entering through the channel reacts to generate high-temperature water and metal oxides. A part of the final products generated in the afterburner is discharged from the body through the nozz

Embodiment Construction

[0013] Further explanation below in conjunction with accompanying drawing

[0014] figure 1 The basic structure diagram of the metal powder unit is shown, in which: 1- is the metal powder, 2- is the aluminum film of the outer packaging of the powder, 3- the welding part of the aluminum film interface, in which the metal powder is packaged in a vacuum state, and the package is isolated after welding It prevents the contact between the external oxidant and the metal particles, and delays the oxidation process of the metal particles. The aluminum film used for packaging is broken under the action of the high-speed rotating turbine of the engine, and the broken aluminum film disintegrates into small units, which participate in combustion under high temperature conditions in the combustion chamber, laying a solid foundation for the standardized packaging of metal powder and the standardized production of cartridges. Basics; classifying encapsulated metal powders helps the aircraft...

Abstract

The invention discloses a metal/water/air reaction feedback type engine and a high-speed sea flitting aircraft with a diving function. Aircrafts using solid fuel always partially or completely use metal powder fuel with high mass energy density ratio and volume energy density ratio to obtain higher speed, and the metal powder fuel is packaged into standard drug column units to be convenient for storage, transport and use. A feeder with an ejector rod and an isolation valve structure is used for feeding metal powder fuel to a combustion chamber of the metal/water/air reaction feedback type engine, the metal powder fuel which is axially fed into the combustion chamber is in reaction with water under the action of a turbine in high-speed rotation to generate hydrogen and metallic oxide, the generated hydrogen is in reaction with oxygen in sucked-in air in an afterburning chamber to generate water, and a small part of combustion end products of the engine is fed back to the main combustion chamber through a feedback passage to participate in the combustion process of the main combustion chamber. A rubber of the aircraft with the engine is positioned below the rear of a body, and the aircraft is provided with equipment such as a water suction pipe, a pull type water suction device and the like and capable of flying above water, on the water surface and underwater.

Description

1. Technical field [0001] The invention relates to a metal powder fuel packaging form, a jet engine using solid fuel, and an aircraft with high-speed sea-skimming navigation and diving function. 2. Background technology [0002] Relying on the reaction between metal and water to provide power, it has the advantages of high energy, high speed, and strong cruising ability. The underwater vehicle that uses metal / water reaction to generate a large amount of heat and gas as the power system can only carry metal powder as a combustion agent. The oxidant and coolant water can be obtained from the marine environment outside the aircraft, which greatly increases the energy reserve of the power system and provides a material basis for high-power long-range aircraft. In order to ensure the energy characteristics of metal / water reactive propellants, the content of solid metal powder in the formula is often high, which successively brings difficult problems such as ignition difficulties,...
