Abstract

Camera di combustione con ugello variabile e lunghezza variabile del vano di combustione, che opera o come camera di combustione di stato reattore oppure in modo combinato come camera di combustione di stato reattore e camera di post combustione di un turbopropulsore, con una parete esterna fissa, delimitante perifericamente il canale di flusso, con un corpo di spostamento, che è disposto nel canale di flusso ed è scorrevole assialmente, nonché con un tubo portante che sostiene il corpo di spostamento e si diparte dall'entrata della camera di combustione.Il canale di flusso delimitato dalla parete esterna si allarga continuamente in direzione di flusso a partire da un piano, che è situato vicino oppure nel piano definito dalla posizione più interna della massima sezione trasversale del corpo di spostamento (Figura 1).Combustion chamber with variable nozzle and variable length of the combustion chamber, which operates either as a reactor state combustion chamber or in combination as a reactor state combustion chamber and post combustion chamber of a turboprop, with a fixed external wall, peripherally delimiting the flow channel, with a displacement body, which is arranged in the flow channel and is axially sliding, as well as with a supporting tube which supports the displacement body and departs from the combustion chamber entrance. flow delimited by the external wall continuously expands in the direction of flow starting from a plane, which is located near or in the plane defined by the innermost position of the maximum cross section of the displacement body (Figure 1).
