    Calculation and Analysis of Initial Conditions at Takeoff of UAV with Springboard
    (Osvita Ukrainy, 2015-10) Tupitsin, Nikolay; Malakhov, Sergey; Shcherbina, Liza
    In article the initial constructive part of springboard is proposed. Also, the calculation and analysis of unmanned aerial vehicle initial conditions at takeoff with spring-loaded final part of springboard are executed. The two technical contrivances as spring-loaded final part were considered: elastically restrained plate and spring-loaded bridge.

    The dynamic segment memory allocation algorithms
    (Osvita Ukrainy, 2015-06) Sineglazov, Viktor; Синєглазов, Віктор Михайлович; Yurchenko, Alexander; Юрченко, Олександр Сергійович; Tupitsin, Nikolay; Тупіцин, Микола Федорович; Kozlov, Anatoliy Pavlovich; Козлов, Анатолій Павлович
    The concept of a generalized fragmentation is introduced. According to the proposed criterion the best algorithm is the algorithm with a smaller value of such fragmentation. Fifteen algorithms of dynamic allocation of the non-paged memory are considered, which, in addition to well-known, include four new algorithms, as well as three algorithms of memory compression.

    Experimental checking of reversibility theorem for axially symmetric body with empennage
    (Osvita Ukrainy, 2016-12) Tupitsin, Nikolay; Тупіцин, Микола Федорович; Ziganshin, Anwar; Зіганшин, Анвар Абдуллович; Stepanenko, Illia; Степаненко, Ілля Олександрович
    Wind tunnel tests were implemented for experimental verification of the reversibility theorem for three various shapes of fore body for an axially symmetric thin body in direct and reverse streams. Be- sides, such tests were implemented for UAV models with three types of wings. Results of investigations showed that the error of execution reversibility theorem consequence can achieve 12.5% at the range of angles of attack from 0 to 20° (accordingly, from 180° to 200°).

    One method to drop the aviation outboard block with variable geometry
    (Osvita Ukrainy, Kyiv, 2016-06) Tupitsin, Nikolay; Тупіцин, Микола Федорович; Yurchenko, Alexander; Юрченко, Олександр Сергійович; Stepanenko, Illia; Степаненко, Ілля Олександрович
    One method to drop the aviation outboard block with variable geometry is proposed. For grounding of this method the calculation and exploration of aerodynamic characteristics of the outboard block, which consists of the outward cylindrical body and inside a sharp body of rotation with a tail plumage, is performed. Estimation of the implementation possibility of a method to drop such block is carried out also.

    Performance of dynamic memory allocation algorithms
    (Osvita Ukrainy, 2015-09) Yurchenko, Alexander; Юрченко, Олександр Сергійович; Tupitsin, Nikolay; Тупіцин, Микола Федорович; Kozlov, Anatoliy; Козлов, Анатолій Павлович; Kemenyash, Yuriy; Кеменяш, Юрій Михайлович
    With the help of modeling there have been investigated 15 algorithms dynamic allocation of the non-paged memory, which, in addition to well-known, include four new algorithms, as well as three algorithms of memory compression.

    THE METHOD OF TAKEOFF AND LANDING UAV WITH HELP SPRINGBOARD
    (Kyiv, “Osvita Ukrainy”, 2014-09) Tupitsin, Nikolay; Тупіцин, Микола Федорович; Dmitrenko, Bogdan; Дмитренко, Богдан Іванович; Ziganshin, Anvar; Зіганшин, Анвар Абдуллович; Stepanenko, Illia; Степаненко, Ілля Олександрович
    The work presents new method takeoff and landing for the unmanned aerial vehicles with help special form of springboard. The calculation of constructive parameters of unmanned aerial vehicle at their application with springboard is carried. The constructive peculiarities of such springboard are analyzed also.
