Measurements have been made of the burning velocity of a hydroxylammonium nitrate-based liquid propellant undergoing combustion in a strand burner. Experiments were conducted at constant pressures of 6.7-34 MPa while the propellant was confined in a strand burner with a 1.8 {times} 1.0-mm rectangular cross section, a size smaller than that used in previous studies. An electric discharge was used to ignite the propellant, which was then observed by high- speed photography. The overall burning velocity in the strand burner was found to be influenced by hydrodynamic effects, resulting in a decrease in the overall burning velocity with an increase in pressure up to 26 MPa. Above 26 MPa instabilities became less important and the burning velocity was independent of pressure, a trend that has not been noted previously. The laminar burning velocity of the propellant was estimated to be 27.3 {plus minus} 0.6 mm/s at pressures of 30-34 MPa.
