And No. HP-8A aviation lubricating oil is to be with normal pressure third-line or decompression first-line lubricating oil fraction as raw material, this fraction section is the key fraction section of high-quality diesel oil, and producing No. 8 aviation lubricating oil will seriously affect the yield of diesel oil, its The economic benefit is greatly reduced. On the other hand, because the No. 8 aviation lubricating oil is a non-special smoke pulling agent, the smoke pulling effect is defective
[0005] The current smoke pulling agents also use chemical substances that can emit smoke, such as sulfuric anhydride, titanium tetrachloride, etc., but they will cause corrosion to the fuselage and are not suitable for long-term use.

Abstract

The invention belongs to the field of a petrochemical industry, and relates to a white contrail production agent for a flight performance. The white contrail production agent for a flight performance comprises a base component, a modified component and colloidal nucleuses. The base component is mineral oil having a distillation range of 200 to 350 DEG C, density of 841.4kg / m<3>, kinematic viscosity of 6.3036mm<2> / s at a temperature of 20 DEG C and a flash point of 135 DEG C. The modified component is mineral oil having a distillation range of 350 to 500 DEG C, density of 0.8657kg / m<3>, kinematic viscosity of 51.101mm<2> / s at a temperature of 20 DEG C and a flash point of 285 DEG C. The white contrail production agent for a flight performance replaces the originally used aviation lubricating oil VIII, guarantees flight training and flight performance tasks of a performance brigade, has large military and economic benefits, realizes high contrail sharpness, and has moderate hang time and good ornamental effects.

Description

technical field [0001] The invention relates to the field of petrochemical industry, in particular to a white smoke pulling agent for air performances. Background technique [0002] There are two main reasons for the white smoke at the tail of the aircraft. One is passive smoke. The high-temperature gas ejected from the engine nozzle of the aircraft is mainly composed of carbon dioxide and water vapor. The water vapor quickly condenses into small water droplets or Ice crystals float in the air, forming white floating objects. Because the flying speed of the aircraft is much greater than the dissipating speed of these floating objects, a white belt is formed. This is called the "wake cloud" of the aircraft, commonly known as "aircraft pulling smoke". The "trail cloud" must be formed when the temperature of the flight environment is low enough, and the flight time is short and extremely unstable. Another situation is to actively pull the smoke, the method is to spray the smok...
