Current liquid propellants are either cryogenic (storage constraints), either extremely toxic (hand領(lǐng) problem). For this purpose, alternative storable propellant are currently being investigated in this work. The sprays generated by a like-impingement configuration have to be ignited. Because the couple of propellants chosen is non hypergolic, the energy of ignition was brought by a torch igniter. The injection conditions of both the propellants and the torch proved to be compatible to ignite the reactants quickly and stabilize the combustion downstream of the impingement point.
