2.1 Diameter. Different correlations to estimate the LH2/LOX fireball diameter were proposed as result of the blast hazards tests of liquid propellant conducted by NASA (Gayle & Bransford, 1965), (High, 1968). In this study, Eq(1) proposed by Hord (1972) was used to estimate the fireball diameter: ≈ 7.93 ∙ /.
