Abstract

Inventia se refera la o metoda si impulsor de excitare a structurilor de aerodina, utilizabile, în special, în domeniul efectuarii încercarilor de flutter în zbor. Metoda de excitare a structurilor de aerodina, conform prezentei inventii, în scopul aplicarii unor impulsuri succesive unei structuri integrale de aerodina aflata în zbor în mod repetat si într-o ordine prestabilita cu obtinerea unor caracteristici de impuls temporale diferite, fortele reactive se obtin prin arderea unor amestecuri combustibile în camera de combustie a unor impulsori gazodinamici si sunt variabile în timp ca marime ca urmare a admisiei a unor cantitati de amestec combustibil diferite atît prin masa cît si prin dozaj. Impulsorul gazodinamic realizeaza metoda de mai sus prin aceea ca pe o placa de baza este montata o duza care primeste amestecul carburant printr-un stut prevazut cu o supapa unisens, capacul impulsorului fiind prevazut la partea sa superioara cu un ajutaj convergent divergent de forma poliedrica care poate fi obturat etans prin intermediul a doua porti situate în sectiunea de intrare a partii convergente a ajutajului si actionate fiecare de cîte un arc elicoidal montat coaxial cu articulatiile portilor, porti prevazute pe fata exterioara cu cîte o gheara de blocare care asigura fixarea acestora în niste degajari practicate în peretele partii convergente a ajutajului sub actiunea a doua zavoare electromagnetice dispuse în peretele superior al capacului.The invention relates to a method and impulse to excite aerodynamic structures, usable, in particular, in the field of flutter flight tests. The method of excitement of the aerodynamic structures according to the present invention for the purpose of applying successive pulses to a fully aerodrome structure in flight repeatedly and in a predetermined order to obtain different temporal impulse characteristics reactive forces are obtained by burning combustible combustible combustion mixtures of gas-dynamic impulses and are variable over time as a result of the intake of different amounts of fuel mixture both by mass and by dosage. The gas conduit impulse performs the above method in that a nozzle is received on a base plate which receives the fuel mixture through a nozzle provided with a unisens valve, the cap of the impeller being provided at its upper part with a divergent converging nozzle of the polyhedral form which can be tightly sealed by means of the two gates located in the inlet section of the convergent nozzle part and each operated by a helical coil mounted coaxially with the joints of the gates, the gates provided on the outer face with a locking claw which secures their fixing in some releases practiced in the convergent nozzle wall of the nozzle under the action of second electromagnetic shutters disposed in the top wall of the cover.
