Book Description
As a result of recent developments in aeronautics and ordnance, a need has arisen for tables of properties of the atmosphere at altitudes in excess of those covered by the existing standard tables (NACA Report No. 218). In order to satisfy this need, the National Advisory Committee for Aeronautics has adopted three temperature-height relationships and one composition-height relationship, and tables based oupon them have been prepared for pertinent properties of the upper atmosphere (from 20 to 120 kilometers in metric units, and from 65,000 to 393,700 feet in British units). In the absence of direct data, such as might be obtained by soundings with high-altitude rockets, the values adopted are based upon existing information obtained by indirect methods of certain quantities. As a consequence, the tables are only tentative.

Charts of Pressure Rise Obtainable with Airfoil-type Axial-flow Cooling Fans
Author: A. Kahane
Publisher:
ISBN:
Category : Aerofoils
Languages : en
Pages : 578
Book Description
Charts are presented to show the pressure rise that is obtainable in an engine-cooling installation with a typical airfoil-type propeller-speed fan. The charts cover fans of the stator-rotor, rotor-stator, and rotor alone configurations, with blades incorporating both the highly cambered 65-series blower-blade sections and the conventional low-cambered airfoil sections. The effects of operation of a geared fan with rotational speeds limited by compressibility considerations and the effects of initial rotational inflow are indicated. Use of the charts to predict the pressure rise obtainable with any fan of the types considered is illustrated in a sample calculation.

Correlation, Evaluation, and Extension of Linearized Theories for Tire Motion and Wheel Shimmy
Author: Robert F. Smiley
Publisher:
ISBN:
Category : Airplanes
Languages : en
Pages : 728
Book Description
A series of systematic approximations to the summary theory is developed for the treatment of problems too simple to merit the use of the complete summary theory, and procedures are discussed for applying the summary theory and its systematic approximations to the shimmy of more complex landing-gear structures than have previously been considered.
