- Abstract
Hybrid propulsion is becoming more and more attractive in both military and commercial fields for its safety, low cost, and throttability. Most of the works on hybrid propulsion so far carried out is connected with the understanding of the combustion of hybrid fuels. However, the ignition of hybrid fuels, as the first step of fuel application, has received little attention. This paper discusses an experimental investigation focused on ignition phenomena of hydroxyl-terminated polybutadiene (HTPB) based fuels, using a continuous CO2 laser with a wavelength of 10.6 m as a radiation source. Gaseous oxygen was selected as oxidizer for ignition tests. Experiments were carried out at the pressure of 0.1 MPa and 1.0 MPa. Ignition delay of HTPB was found to decrease with the increasing of radiant flux, and the relationship between ignition delay (ti) and incident radiant flux (q) can be described as , with n= 1.16 at 0.1 MPa and n= 1.00 at 1 MPa. Ignition delay of HTPB based fuels did have a dependence on pressure. Mg, MgB, and am_ Al powers are demonstrated to have a positive effect on decreasing ignition delay of HTPB fuels.
