Airfoil Shapes - Dimensioning of Turbine Engine

1959-02-01
CURRENT
ARP265A
This Aeronautical Recommended Practice provides a standard method for locating and dimensioning the airfoil portions of parts such as blades, and vanes. This method will apply to blades, or vanes with or without a base. The forms of attachment are varied; therefore, the blade bases shown in the following figures are for illustration only. All dimensions and notes shown pertaining to the common functional point, line or plane are considered to be applied to a datum, on or off the part, irrespective of the form of attachment.

Contamination Studies of Aircraft Greases

1995-05-01
CURRENT
AIR42
Certain techniques involved in determining the dirt or abrasive content of aircraft greases are considered inadequate. It is desirable to develop a method of analysis which will definitely identify the quantity, size, and degree of abrasiveness of foreign substances in lubricating greases.
