Rapid Chemical Test for the Identification of Chromium-Molybdenum Steel

Description: This note describes a simple, rapid, qualitative test which can be applied to solutions of drilling or chips for the identification of chromium-molybdenum steel. The test is based on the orange-red compound which is formed when thiocyanate and inequivalent molybdenum react. This test is much more reliable than the potassium ethylxanthate test which has been recommended for a like purpose. A list of the apparatus and reagents which are required, and a description of the procedure follows.

Effect of engine operating conditions on the vaporization of safety fuels

Description: "Tests were conducted with the N.A.C.A. combustion apparatus to determine the effect of compression ratio and engine temperature on the vaporization of a hydrogenated "safety fuel" during the compression stroke under conditions similar to those in a spark-ignition engine. The effects of fuel boiling temperature on vaporization using gasoline, safety fuel, and Diesel fuel oil was also investigated. The results show that increasing the compression ratio has little effect on the rate of fuel vapor… more

The Compressive Strength of Duralumin Columns of Equal Angle Section

Description: "This report presents a chart giving the compressive strength of duralumin columns of equal angle section. The data used in the construction of the chart were obtained from various published sources and were correlated with theory in the range where secondary failure occurred. Appendices are included giving excerpts from Army and Navy specifications for duralumin and approximate formulas for the properties of the equal angle section" (p. 1).

Tests on thrust augmenters for jet propulsion

Description: "This series of tests was undertaken to determine how much the reaction thrust of a jet could be increased by the use of thrust augmenters and thus to give some indication as to the feasibility of jet propulsion for airplanes. The tests were made during the first part of 1927 at the Langley Memorial Aeronautical Laboratory. A compressed air jet was used in connection with a series of annular guides surrounding the jet to act as thrust augmenters. The results show that, although it is possible t… more

General Potential Theory of Arbitrary Wing Sections

Description: The problem of determining the two dimensional potential flow around wing sections of any shape is examined. The problem is condensed into the compact form of an integral equation capable of yielding numerical solutions by a direct process. An attempt is made to analyze and coordinate the results of earlier studies relating to properties of wing sections. The existing approximate theory of thin wing sections and the Joukowski theory with its numerous generalizations are reduced to special cases… more

Tests of N.A.C.A. airfoils in the variable-density wind tunnel Series 24

Description: "This note is the fifth of a series covering an investigation of a number of related airfoils. It presents the results obtained from tests of a group of six low-cambered airfoils in the variable-density wind tunnel. The mean camber lines are identical for the six airfoils and are of such a form that the maximum mean camber is 2 per cent of the chord and is at a position 0.4 of the chord behind the loading edge. The airfoils differ in thickness only, the maximum-thickness/chord ratios being 0.06… more

Valve Timing of Engines Having Intake Pressures Higher Than Exhaust

Description: Note presenting an investigation to determine the possible improvement in performance by using a large amount of valve overlap on a supercharged engine. A series of tests was made on the NACA universal single-cylinder engine of 5-inch bore and 7-inch stroke with varying amounts of overlap from 0 to 100 degrees at five different intake pressures.

The use of large valve overlap in scavenging a supercharged spark-ignition engine using fuel injection

Description: From Summary: "This investigation was conducted to determine the effect of more complete scavenging on the full throttle power and the fuel consumption of a four-stroke-cycle engine. The NACA single-cylinder universal test engine equipped with both a fuel-injection system and a carburetor was used. The engine was scavenged by using a large valve overlap and maintaining a pressure in the inlet manifold of 2 inches of mercury above atmospheric. The maximum valve overlap used was 112 degrees.

The Crystal Cavities of the New Jersey Zeolite Region

Description: From abstract: The crystal cavities present in the mineral complex of the New Jersey traprock region have long excited the interest of mineralogists. In 1914 Fenner made the first detailed and comprehensive study of these cavities and suggested that babingtonite was the original mineral. Soon after this anhydrite was found occupying parts of some of the cavities at one of the quarries. At this time, too, Wherry concluded that glauberite was the original mineral of some of the cavities because o… more

How to Control Billbugs Destructive to Cereal and Forage Crops

Description: Revised edition. "Billbugs destroy or injure corn, wheat, rye, barley, oats, timothy, blue grass, Bermuda grass, Johnson grass, rice, sugar cane, peanuts and chufa. The most conspicuous damage by the adult billbugs is done to young corn plants. The most costly damage is undoubtedly that done by the larvae or grubs in cutting the underground portions of plants, especially those grown for hay and pasture. Billbugs have only one generation yearly and are generally dependent on grass sods or wild s… more
