Granted: 2020-08-26
Abstract: FIELD: transportation. 
     SUBSTANCE: existing vehicle braking systems do not reduce vehicle braking distance for fast stopping, especially in case of emergency. When the vehicle is equipped with energy-condensed systems (devices), for example, with the required capacity pyrocartridges, which, when triggered, eject the charge upwards, reactive force directed downwards for a certain period of time, which increases the vehicle normal pressure force on the movement surface. This provides increase in the friction force inhibiting the vehicle. Vehicle is equipped with energetically compensated devices configured to eject charge in direction of motion. This ensures kinetic energy retardation, which contributes to vehicle stop. 
     EFFECT: design of a device providing for reduction of braking distance during fast (emergency) stop of a vehicle, including braking of aircraft after landing.

Abstract: FIELD: agriculture, soil protection.SUBSTANCE: invention relates to agriculture, in particular to methods for combating water erosion of soils on slopes and preventing the growth of ravines. The movement of surface runoff is redirected when it passes through the material with a high degree of filtration, deep into the trench, where it is captured by organic water-absorbing filler, coir. The geotextile prevents the water flow from filtering towards the top of the ravine, and the presence of a batter board screen protects the trench slope and the water retaining shaft from destruction, which provides additional stability of the structure to the water flow. The application of the invention will prevent the growth of the top of ravines and water erosion of soils by regulating the surface runoff by intercepting and redirecting the movement of the water flow and increasing the volume of water absorption. The use of a screen will protect the slope from erosion and create an obstacle to the movement of water down the slope, as well as provide additional stability of the structure. Coir absorbs large volumes of water, followed by its gradual return. The use of natural materials in the construction helps to preserve the environmental characteristics of the area and improve the condition of the soil, does not require their disposal after the end of their service life.EFFECT: application of the invention will prevent the growth of the top of ravines and water erosion of soils by regulating the surface runoff by intercepting and redirecting the movement of the water flow and increasing the volume of water absorption.1 cl, 1 dwg
