Micarta Propellers III : General Description of the Design

The design of propellers made of Micarta is discussed. The advantages of the material are noted, especially as compared with wood. The design changes necessitated by the use of Micarta are discussed with reference to the hub boss, the narrowing of the blade tips, the thinning of the blades, the angles of the leading and trailing edges, and the adjustment of the pitch. Results of flight tests show that the Micarta propeller gave a top speed of 2 miles per hour more than the wooden propeller while turning about 120 r.p.m slower, with about the same rate of climb. At top speed, the Micarta propeller shows an improvement of about 7 percent in fuel economy, although the plane is flying 2 miles per hour faster

Micarta propellers IV : technical methods of design

A description is given of the methods used in design of Micarta propellers. The most direct method for working out the design of a Micarta propeller is to start with the diameter and blade angles of a wooden propeller suited for a particular installation and then to apply one of the plan forms suitable for Micarta propellers. This allows one to obtain the corresponding blade widths and to then use these angles and blade widths for an aerodynamic analysis

Micarta propellers I : materials

Here, values for tension, compression edgewise of laminations, and transverse flatwise of laminations are given for Micarta made with various kinds of sheet material. The corresponding values for white oak are given for comparison. It was found by destructive and service tests that Micarta made with a good grade of cotton duck will give satisfactory service with most designs. In propellers having detachable blades, it is desirable that the root of the blade be of a small cross section to decrease the weight of the metal hub. Here the use of the special fabric or wood veneer offers advantages due to greater tensile strength. These materials, especially the wood veneer, produce stiffer blades than duck. This is also a value in controllable and reversible pitch designs where it is desirable that the plan form of the blades be symmetrical

Manufacturing milk producers in Henry County, Tennessee : Problem A: Characteristics of Henry County manufacturing milk producers and their farms : Problem B: Management practices of Henry County manufacturing milk producers : Problem C: Factors influencing dairy management practice adoption by Henry County manufacturing milk producers : three related special problems in lieu of thesis /

In the four year period, 1962-65, dairying ranked third in importance as a source of agricultural income in Tennessee (20:1). * Annual receipts averaged about 85 million dollars for the period of 1961-65. Also, there were approximately 444, 000 dairy cows in Tennessee in 1965. Average milk production per Tennessee cow that year was only 5,000 pounds, while the average American cow was producing 8, 080 pounds (18:1) . Some research (19:1) suggests that manufacturing milk production per cow of less than 5, 500 pounds is unprofitable, and that cows producing below that amount should be culled and replaced. Henry County is located in the northeast corner of the Western Division of Tennessee. It is bordered on the north by the state of Kentucky, on the east by the Tennessee River and by Benton County. The south boundary is with Carroll County and the west boundary with Weakley County. The· agriculture of the county is rat her diversified, a little more than one-half of the agricultural income coming from the sale of livestock pro ducts and a little under one-half coming from the sale of crops. Dairying ranks third in importance and is exceeded only in dollar value by the sale of cattle and calves and by: crops (5:2 17). Manufacturing milk production started on the increase in 1950 when Pet Milk Company located a buying plant at Paris, Tennessee. Three field men were assigned to Henry and six surrounding counties to establish routes and work with producers on recommended management practices leading to high prod suction
