Figure 102: Two Tanks For Pressure-Operated Rocket, Winter 1926, Esther C. Goddard

March 16, 1926: The First Liquid-Propellant Rocket Launch

Photograph of two tanks for a pressure-operated rocket. The tank on the right would hold liquid oxygen that created pressure once vaporized (a disassembled view can be seen in Figure 103), and the smaller gasoline tank is on the left. These tanks would be modified in several ways leading up to the March 16, 1926 launch. Photographs of the subsequent tanks can be found in Figure 109, 110, 111, 112, 113, 114, and 115.

These were the first pressure tanks made following December 6, 1925 (the day Robert Goddard achieved the first …

Development Of A Liquid Propelled Rocket, Section Iii: December 1925 - May 1926 [Excerpt], Robert H. Goddard

March 16, 1926: The First Liquid-Propellant Rocket Launch

Excerpt from a report written by Robert Goddard tracing his development of the first liquid-propelled rocket. The full report covers 1921 to 1929. This excerpt contains most of part three which covers everything following December 6, 1925 (the day Robert Goddard achieved the first liquid-fuel rocket to lift its own weight) and May 1926. This excerpt contains everything up through March 16, 1926, the day Goddard saw the world's first successful launch of a liquid-propelled rocket.

The December 6, 1925 test used the pumps, engines, and other moving parts Goddard spent years working with and developing. Following this test, Goddard …

A Study Of Light Metals And Alloys At Low Temperatures, Donald E. Higgins

Historical Dissertations & Theses

Although the determination of the strength of metals and alloys at ordinary temperatures is an everyday matter, very little work has been done to determine their strength and elasticity at very low temperatures. Mallock and Schaefer have investigated certain metals at the temperature of liquid air, and have deduced formulae to express the relation between elasticity and temperature, while Andrade has given an expression for the flow of metals under large constant stress. This work was intended in part to find out if their formulae would apply to the very light alloys used here. Another object was to find, if …

An Experimental Study Of The Cathode Fall In Helium And Argon With Wire Cathodes, L. G. Raub

University Studies (University of Nebraska) (1888–1984)

It was recognized rather early in the study of the phenomena of discharge of electricity through gases that the ordinary laws of conduction as found in solid and liquid conductors are not applicable to gases. It was shown by Zeleny and independently by Child that Ohm's law by no means represents the distribution of potential between electrodes in an ionized gas, but that the potential gradient is large in the vicinity of the electrodes, and not uniform throughout the space between them. When the pressure of the gas surrounding the electrodes is reduced to one or two millimeters and a …

Studying Properties Of Xenon Doped Argon And Developing Optical Simulation Techniques For The Legend Collaboration, A Neutrinoless Double Beta Decay Experiment, Neil Christopher Mcfadden Dr

Physics & Astronomy ETDs

Neutrinoless double beta decay is a hypothesized lepton-number-violating process in which two neutrons decay to two protons, producing two electrons but no electron antineutrinos. The LEGEND collaboration will search for this decay in ⁷⁶Ge. To improve the argon active veto for LEGEND-1000, xenon doped argon was explored as an alternative active volume. Simulations using argon doped with 10 ppm xenon and pure liquid argon were used to predict the light yield from cosmic muons in a 100 liter cryogenic vessel. The simulations predicted that xenon doping would yield 1.83+/-0.02 more light, while an increase of 1.81+/-0.05 was measured. From …
