DRIVE, ITS APPLICATION IN GAS TURBINE ENGINE FOR OPENING/CLOSING OF FLAPS, AND TURBOJET Russian patent published in 2013 - IPC F02C6/08 F02C9/18 F01D17/14 

FIELD: engines and pumps.

SUBSTANCE: proposed drive comprises, at least, one drive mechanism made from alloy with double-sided memory effect. Said drive mechanism has first stable state at first preset temperature whereat it opens or closes flaps and second stable state at second preset temperature whereat it performs second opening/closing jobs different from the first operation. Besides, it incorporates temperature control means to adjust it to first or second preset temperature, control valve and connection tube connected with the latter. Drive mechanism has first feed line communicated with first fluid source to be adjusted to first preset temperature and second feed line communicated with second fluid source to be adjusted to second preset temperature. Said first and second feed lines are connected with control valve. Besides, this invention covers application of said drive device tor opening/closing gas turbine engine flaps. Note here that engine comprises, at least, one structural element where through fluid flow passes and whereat inlet is arranged for fluid to be kept at preset inlet temperature. As well, engine comprises outlet whereat fluid is kept at preset outlet temperature. Said first fluid source represents inlet or outlet source while another fluid source represents another fluid inlet or outlet source. Invention covers also turbojet including primary gas-air efflux channel with secondary gas-air efflux channel and discharging system with, at least, one discharge flap to deflect air from primary gas-air channel to secondary channel, and, at least, one above described drive device.

EFFECT: smaller overall dimensions and weight.
