Abstract: A SABRE cycle model is reconstructed with the method of thermodynamic cycle analysis combined with CFD simulations. Considering characteristics of airbreating and rocket modes and advantages of thrust to weight and specific impulse of SABRE engine required by a horizontal takeoff, reusable aircraft, some possible vehicle applications are provided and analyzed with published documents reviewed and taken into consideration. It reveals that the SABRE engine may be used to different horizontal takeoff vehicle applications, meaning which might be used not only to propel hypersonic cruise vehicle with pure airbreathing mode, but also to propel a suborbital vehicle lifting off an orbit or a striking payload in suborbital space, or to propel a TSTO vehicle to a higher Mach separating point with working in both airbreathing and rocket modes.
