Materials for Liquid Propulsion Systems
https://ntrs.nasa.gov/search.jsp?R=20160008869 2019-08-29T17:47:59+00:00Z CHAPTER 12 Materials for Liquid Propulsion Systems John A. Halchak Consultant, Los Angeles, California James L. 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. -

We are entering a period that marks fifty years since the beginning of World War I1 and its after- math. The 1940s and 1950s marked a period of unprecedented national growth and development in urbanization, residential and commercial construction, scientific and tech- nological development, and national infrastructure. The Nation's historic preservation policy was a response to those developments and their effects on America's historic resour- ces. -

William R. Lucas Oral History Interview
INTERVIEW WITH DR. WILLIAM LUCAS INTERVIEWED BY A. DUNAR.Ai~D S. WARING 19JUNE 1989 HUNTSVILLE, ALABAMA 1. DUNAR: Why did you come to Huntsville? Did you know about the activities of the von Braun team before you came here or did you come because of a connection with the Army? What drew you here to Huntsville? 2. LUCAS: I didn't have any connection with the Army. When I came here I did know something about the activity that was going on. I was in graduate school at Vanderbilt University and one of my professors there was a consultant down here. I think it was to the Thiokol corporation, but I am not positive of that. He was a consultant and was aware of what was going on down here and suggested that I ought to look into the situation down here. It appeared to him to be an exciting new prospect of research and activity. That was my introduction to [Huntsville]. 3. DUNAR: When you arrived here it seems, (just from an outsiders perspective) like an unusual thing, you had three different groups here: civilians, Army and the von Braun Team. Would you describe how that interrelationship worked? 4. LUCAS: You did have the Army. I don't know if I would divide them quite as you did here. There was the Army program here, the rocket program that was being placed here. The Arsenal as we now know it, the Redstone Arsenal, early on was two arsenals, the Redstone Arsenal and the Huntsville Arsenal. By the time we came here, it was all called Redstone Arsenal. -
