Context. Within the framework of the accepted simplifying hypotheses, an approximate scheme of calculation of the parameters of the active and passive sections of the trajectory is proposed, which allow to study the trajectory properties of the existing a... see more

Fuel is one of the most critical needs for the community in carrying out various household activities dominated by fuel oil. Meanwhile, the availability of fuel is increasingly running low. Most people in the Botumoito area in Gorontalo province work in t... see more

The paper describes the system of analytical control of environmental objects in places of hydrazine-based rocket fuel spill. The system is totally based on a method of screening of transformation products of 1,1-dimethylhydrazine allowing to collect comp... see more

Fuel Flow controller based ramjet propulsion system have a flexibility to change rocket velocity depending on guidance requirement by controlling the fuel flow rate as a function of atmospheric conditions like altitude, Mach no. and angle of attack. In th... see more

A series of paraffin-based hybrid rocket fuel has been studied experimentally in a laboratory-scale motor. To enhance the regression rate of paraffin solid fuel, three types of grain configurations: Cylindrical, star, and helical grain configurations o... see more

This paper presents the design of a hybrid rocket motor and the experiments carried out for investigation of hybrid combustion and regression rates for a combination of liquid oxidiser red fuming nitric acid with solid fuel hydroxyl-terminated Polybutadie... see more

The main components of high-energy compositions are nitramines: octogen (HMX) & hexogen (RDX). The solution to the problem of the lack of these components is possible through the use of returnable resources, which are obtained using a certain technology f... see more

Abstract. The weighted moving average (WMA) method is a method of calculating data forecasting values through moving average values that are given different weights for each time period. The Covid-19 pandemic has had a considerable impact on the State of ... see more

Currently, plastic waste is a very serious threat because plastic waste pollution can harm all living things around and also harm the environment. The increasing volume of plastic waste is due to the lack of processing technology, so that the volume of pl... see more
