Deflecting pipe for rocket engine using solid propellant - has side valve with vent in inside of jet wall which is closed by pressure differential

The control system has a valve located between the combustion chamber (20) and the nozzle area of the jet. The valve (10) has a needle (11) sliding in the cylinder (12). When the valve is closed, the passage (13) is blocked. With the valve opened the gas may flow from the area (21) to the side of th...

Beschreibung
Zusammenfassung:	The control system has a valve located between the combustion chamber (20) and the nozzle area of the jet. The valve (10) has a needle (11) sliding in the cylinder (12). When the valve is closed, the passage (13) is blocked. With the valve opened the gas may flow from the area (21) to the side of the jet. The vent (16) is connected to the control valve (18) which produces a jet at the outside of the main jet. The differential pressure across the valve maintains it normally closed. DIVERGENT A VANNE INCORPOREE.UNE VANNE 10 EST LOGEE DANS UN PROPULSEUR ET COMPORTE UNE PIECE MOBILE 11 POUR FERMER OU OUVRIR UN PASSAGE D'INJECTION 13 ENTRE LA CHAMBRE DE COMBUSTION 20 ET LE DIVERGENT DE LA TUYERE 30. UN CLAPET EXTERIEUR 18 EST PREVU AU BOUT D'UN CONDUIT D'ECHAPPEMENT 16 POUR PROVOQUER, LORSQU'IL EST MANOEUVRE, L'ETABLISSEMENT D'UNE PRESSION DIFFERENTIELLE QUI COMMANDE LE DEPLACEMENT DE LA PIECE 11.L'INVENTION EST UTILISABLE POUR COMMANDER LA DEVIATION DU JET DANS UNE TUYERE DE PROPULSEUR A PROPERGOL SOLIDE PAR INJECTION DE GAZ CHAUDS DANS LA TUYERE.
