Method for detection of ignition of mixture of propellants in combustion chamber of jet engine of rocket, involves determining ignition of mixture of propellants when reference variable has reached predetermined threshold

摘要

The method involves forecasting a beginning (t all debut) of a temporal beach of ignition according to a set of initial conditions. A physical parameter (PRGC) is measured in a combustion chamber. A reference variable (PRGC f der) is calculated according to a signal corresponding to the physical parameter. Ignition of mixture of propellants is determined when the reference variable has reached a predetermined threshold after beginning of the temporal beach of ignition. Independent claims are also included for the following: (1) a system for detection of ignition of a mixture of propellants (2) a computer program comprising instructions for performing a method for detection of ignition of a mixture of propellants (3) a data storage medium comprising instructions for performing the method for detection of ignition of a mixture of propellants.
