Script Are reusable rockets a sustainable possibility for the future? What are rockets? Rocket technology is extremely wasteful, and being a one shot wonder, they show no promise of a sustainable future. When a rocket is launched, it is propelled based upon newton’s 3rd law of motion; “For every action, there is an equal and opposite reaction.” This is done by using on board propellant which is then used to create thrust from a rocket engine, by ejecting thrust in the opposite direction to the rocket, it is propelled forwards at very high speeds. This propellant is either a liquid fuel or solid fuel (Braeunig, June 5th 2016). However, due to the rockets mass being more than 90% propellant, once they are launched, the empty rocket is then…

Rockets are more than just a machine. It’s a machine, which can travel a great amount of height, and distance where once the human race thought it was impossible. There are actually many different types of rockets such as, balloon rockets, water rockets, and skyrockets. Every rocket plays the same role, taking you to places whether up into space or under the deep sea. Rockets are fascinating machines that changed history. Rockets have helped us explore and learn about the world we live in. We…

has same in magnitude but different in direction. The exhaust is formed entirely from propellants carried within the rocket before it isuse in every rockets and rocket engines work by action and reaction.This rocket engines push rockets forwards simply by throwing their exhaust backwards extremely fast.Application of rockets can be use as weaponary, rescue mission, launch vehicle, human spaceflight, also for hobby activities. Rocket motor usually refers to solid propellant rockets engines and…

1.4.2.2 Oxidizer The oxidizer is an another basic ingredient of solid propellant which produces high energy during combustion of composite solid propellants, which can be referred to as the substance that whose function is the oxidizing materials or supply of oxygen for deflagration of a propellant. Ammonium perchlorate (AP) is the most commonly used oxidizer in solid propellant applications, which replaced Potassium Perchlorate in the late 1940’s. AP was used as an oxidizer in various types of…

in large number of quantities all around the world. These bottles contain the material to be dispensed, a liquid propellant gas such as dichlorodifluoromethane and usually a solvent to reduce the material to spraying consistency. Shuzo Kaneko, Kamakura and Shigefumi 2002 described Aerosol spray guns as typically used in different areas where we need to fill large patterns. An aerosol spray gun transforms liquid paint into mist. It jets out the aerosol paint and directs patterning air to the…

These collisions apply a pressure per unit area and cause the gases to occupy a volume. The "head space" of an aerosol can is filled with extremely pressurized propellant found in a gas form and goes with Henry's law as an equivalent quantity of this propellant is deliquesced in the product itself. As soon as the nozzle gets depressed, the pressure of the propellant forces the product out through the nozzle. Both the pressure and volume are affected by temperature and the relationship between…

The injection hole pattern on the face of injector provide propellant distribution form the injector inlet to all of the injector holes. High passage velocities will cause uneven flow through the injection holes and will also disturb the distribution and the composition. When talking about engine performance injector has main impact on the engine than any other component. While designing injector an important factor which is kept in mind is the combustion stability. The injector will have only…

Over view of Meter dose Inhaler Regulation in US and EUROPE. Introduction A metered-dose inhaler (MDI) is a device that delivers a specific amount of medication to the lungs, in the form of a short burst of aerosolized medicine that is usually self-administered by the patient via inhalation. It is the most commonly used delivery system for treating asthma, chronic obstructive pulmonary disease (COPD) and other respiratory diseases. Metered-dose inhaler products contain therapeutically active…

The Evolvable Mars Campaign Introduction There are two transportation methods of the approaches to the mars. The two methods are the SEP-Chem and the Hybrid method. In the SEP-Chem architecture, the system destination and the propellant return or the stages are pre-deployed proceedings to the troop leaving by the spacecraft of the cargo and it is a solar electric. While in the Hybrid approach, the systems of the destinations are also installed before the troop leave via the SEP, but the…

The direction of force can be determined using the right hand palm rule. The design of the railgun is illustrated in Figure 2. After much research, the U.S navy has a goal to deploy a 64 Mega joule cannon that will utilise tungsten slugs and fire targets with speeds around 5,800 metres per second, with 10 shots fired a minute. At this rate, the railgun will accurately strike a 5-metre wide target from approximately 200 nautical miles away. Conventional weapons generally require a propellant to…
