دانلود کتاب Valveless Pulsejet Engines 1.5

توضیحاتی در مورد کتاب به زبان اصلی :

35 с.The idea that the simplest engine an enthusiast can make at home is a jet engine will sound strange to most people - we perceive jet engines as big complex contraptions pushing multi-million dollar aircraft through the skies. Yet, this is completely true. In its most basic form – the valveless pulsejet - the jet engine can be just an empty metal tube shaped in a proper way. Everyone able to cut sheet metal and join metal parts can build one in a garage or basement workshop.
Due to peculiar historical circumstances, this interesting fact has escaped popular attention. It is not familiar even to enthusiasts of jet propulsion. You are not very likely to see or hear jet engines roaring in people’s back yards on Sunday afternoon. Few if any people can be seen flying aircraft powered by jet engines they have built themselves.
This document aims to help change that. However, it is not a how-to primer. It is an attempt to describe and explain the valveless pulsejet in principle. It also offers a rough sketch of the amazing variety of layouts the inventors and developers have tried during the long but obscure history of this device.
My aim is to inspire, rather than teach. My goal is to demonstrate that jet power is accessible to everyone in a great variety of simple ways. Should you find the inspiration, plenty of information on the practical steps towards jet power will be available elsewhere.
