    A Model Of Small Airship’s Propelling

    Full text link
    For the purposes of development of a small and autonomously operated airship, a need to create a model of its propelling and motion has arisen. Being described within this paper, the model defines the requirements that are imposed to motors, propellers and the airship's controlling system. The model is based on a typical design of a small airship, that consists of two main propellers, being placed symetrically according to the gondola beneath the airship's bladder, and one tail propeller that is placed transversely at the airship's tail. According to this model, forces needed to move the airship in the desired direction can be estimated as well as the power consumption of the motors and angular velocity of the propellers. Although the dynamic model of the airship would exceed the framework of this paper, it is also described in broad terms and the results of two main simulations are presented hereby. The simulations describe the behavior of the airship in case of forward acceleration and braking as well as in case of yawing with such braking that ensures reaching of the desired yawing angle. © ECMS Valeri M.

    This nomenclature for aeronautics was prepared by a Special Conference on Aeronautical Nomenclature by the executive committee of the National Advisory Committee for Aeronautics at a meeting held on August 19, 1924, at which meeting Dr. Joseph S. Ames was appointed chairman of the conference. The conference was composed of representatives of the National Advisory Committee for Aeronautics and specially appointed representatives officially designated by the Army Air Service, the Bureau of Aeronautics of the Navy Department, the Bureau of Standards, the American Society of Mechanical Engineers, the Society of Automotive Engineers, and the Aeronautical Chamber of Commerce. The purpose of the committee in the preparation and publication of this report is to secure uniformity in the official documents of the government and, as far as possible, in technical and other commercial publication

    The nomenclature for aeronautics presented in this Report No. 474 is a revision of the last previous report on this subject (i.e., Report no. 240.) This report is published for the purpose of encouraging greater uniformity and precision in the use of terms relating to aeronautics, both in official documents of the Government and in commercial publications. Terms in general use in other branches of engineering have been included only where they have some special significance in aeronautics, or form an integral part of its terminology
