History of Rocket Technology
CHAPTER 1 History of Rockets 1. 1. INTRODUCTION Action-Reaction Principle Take any technology and you always find that its practical demonstration had been realized much before the theory was established. However, you may note that the fast and effective refinement of a technology begins only after its theory, explaining the underlying basic principles, has been established. The action-reaction principle that is fundamental to jet propulsion, which includes airbreathing- as well as rocket-propulsion, was theoretically explained only in 1687 by the English scientist Sir Isaac Newton by his famous publication “Philosophiae Naturalis Principia Mathematica (“Mathematical Principles of Natural Philosophy”). But, approximately 2100 years before this, Archytas, a Greek philosopher, mathematician, astronomer, statesman, and strategist, had demonstrated the action-reaction principle by his toy pigeon in the city of Tarentum, Fig. 1. 1. Archytas suspended on a wire his wooden pigeon that contained hot steam at an elevated pressure in its belly cavity. The other end of the wire was hooked on to the top of a tall pole. On releasing a plug, a jet of steam escaped through a hole from the rear of the pigeon to produce a thrust that made the toy pigeon fly in circles around the pole. Thus Archytas mystified and amused the citizens of Tarentum by his flying toy- pigeon and demonstrated the fundamental principle of propulsion: “every force has an equal and opposite reaction”. The second recorded-demonstration of the action-reaction principle was in the first century B.C. Hero of Alexandria, a Greek mathematician 1 and scientist, constructed a device known as aeolipile. -

Impressed with his work, Dornberger recruited von Braun to aid in developing liquid-fueled rockets for the military in August Originally known as the A4, the V-2 featured a range of miles Repairing the Panzers: Volume 2: German Tank Maintenance in World War 2 a maximum speed of 3, mph. Its 2, pounds of explosives and liquid propellant rocket engine allowed Hitler's army to employ it with deadly accuracy. Commencing work with a team of 80 engineers at Kummersdorf, von Braun created the small A2 rocket in late While somewhat successful, the A2 relied on a primitive cooling system for its engine. Intended to be a smaller prototype of the A4 war rocket, the A3's engine nonetheless lacked endurance, and problems quickly emerged with its control systems and aerodynamics. Accepting that the A3 was a failure, the A4 was postponed while the problems were dealt with using the smaller A5. The first major issue to be addressed was constructing an engine powerful enough to lift the A4. This became a seven-year development process that led to the invention of new fuel nozzles, a pre-chamber system for mixing oxidizer and propellant, a shorter combustion chamber, and a shorter exhaust nozzle. Next, designers were forced to create a guidance system for the rocket that would allow it to reach the proper velocity before shutting off the engines. -
Materials for Liquid Propulsion Systems

Cannon NASA Marshall Space Flight Center, Huntsville, Alabama Corey Brown Aerojet-Rocketdyne, West Palm Beach, Florida 12.1 Introduction Earth to orbit launch vehicles are propelled by rocket engines and motors, both liquid and solid. This chapter will discuss liquid engines. The heart of a launch vehicle is its engine. The remainder of the vehicle (with the notable exceptions of the payload and guidance system) is an aero structure to support the propellant tanks which provide the fuel and oxidizer to feed the engine or engines. The basic principle behind a rocket engine is straightforward. The engine is a means to convert potential thermochemical energy of one or more propellants into exhaust jet kinetic energy. Fuel and oxidizer are burned in a combustion chamber where they create hot gases under high pressure. These hot gases are allowed to expand through a nozzle. The molecules of hot gas are first constricted by the throat of the nozzle (de-Laval nozzle) which forces them to accelerate; then as the nozzle flares outwards, they expand and further accelerate. It is the mass of the combustion gases times their velocity, reacting against the walls of the combustion chamber and nozzle, which produce thrust according to Newton’s third law: for every action there is an equal and opposite reaction. [1] Solid rocket motors are cheaper to manufacture and offer good values for their cost. -
PEENEMUENDE, NATIONAL SOCIALISM, and the V-2 MISSILE, 1924-1945 Michael
ABSTRACT Title of Dissertation: ENGINEERING CONSENT: PEENEMUENDE, NATIONAL SOCIALISM, AND THE V-2 MISSILE, 1924-1945 Michael Brian Petersen, Doctor of Philosophy, 2005 Dissertation Directed By: Professor Jeffrey Herf Departmen t of History This dissertation is the story of the German scientists and engineers who developed, tested, and produced the V-2 missile, the world’s first liquid -fueled ballistic missile. It examines the social, political, and cultural roots of the prog ram in the Weimar Republic, the professional world of the Peenemünde missile base, and the results of the specialists’ decision to use concentration camp slave labor to produce the missile. Previous studies of this subject have been the domain of either of sensationalistic journalists or the unabashed admirers of the German missile pioneers. Only rarely have historians ventured into this area of inquiry, fruitfully examining the history of the German missile program from the top down while noting its admi nistrative battles and technical development. However, this work has been done at the expense of a detailed examination of the mid and lower -level employees who formed the backbone of the research and production effort. This work addresses that shortcomi ng by investigating the daily lives of these employees and the social, cultural, and political environment in which they existed. It focuses on the key questions of dedication, motivation, and criminality in the Nazi regime by asking “How did Nazi authori ties in charge of the missile program enlist the support of their employees in their effort?” “How did their work translate into political consent for the regime?” “How did these employees come to view slave labor as a viable option for completing their work?” This study is informed by traditions in European intellectual and social history while borrowing from different methods of sociology and anthropology. -

The Rocket That Started It
The V-2 - The Rocket That Started It All Presented by John Halchak Retired Senior Fellow in the Engineering department of Rocketdyne (now named Aerojet Rocketdyne), Canoga Park, California The German A-4 rocket was renamed by the Nazi propaganda minister Joseph Goebbels, as “Vengeance weapon No. 2”, and became commonly known as the V-2. It was the world’s first true ballistic missile. It also was the first man-made vehicle to enter outer space. Over 3000 of these were launched at various targets in WWII, killing perhaps 9000 people. However, far more slave laborers died producing it, perhaps as many as 25,000. Although rushed into production, the V-2 essentially was a research vehicle, full of design and production flaws. Materials shortages in Germany required its designers to utilize some creative substitutions in material selections. It was a leap in technology, achieved in a very short time, yet most of its design features still are common in today’s launch vehicles. Although it was a technological achievement, the fact cannot be ignored that it was produced in support of one of history’s most evil regimes, and its mass production plant involved untold human suffering and the death of thousands. The engineers developing the V-2 had been attracted by the prospect of exploring space; they found too late that they had entered into a Faustian bargain from which they could not escape even if they had wanted to. Afterwards, the V-2 was the genesis for both the American and Russian space and missile programs, and eventually every other country’s program. -
