Researchers at NASA's Johnson Space Center have developed an improved process for computing aerothermodynamic surface heating. The modified Boundary Layer Integral Matrix Procedure – Kinetic (BLIMPK) code offers the capability to update surface material properties to model damage and repairs to the space shuttle orbiter's thermal protection system (TPS). The code uses streamline inputs along with the BLIMPK code to analyze changes in the chemical heating on the orbiter's TPS due to changes in the surface chemical properties. The modified two-layer approach consists of extracting streamline properties from a viscous non-equilibrium solution instead of a standard inviscid (Euler) solution. This modification allows BLIMPK to resolve the adverse pressure gradient when a streamline passes through the shock-shock interaction region on the orbiter wing leading edge. This software may be released for U.S. Government purposes only.

Benefits

  • Efficient: Allows re-entry trajectories to be completed well in advance of missions
  • Flexible: Accepts updates to the surface material recombination coefficients at each streamline station

Applications

  • Hypersonic aircraft
