Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

Results of additional improvements to the numerical solution methods used in RETRAN are presented. The new solution methods remove time-step size limitations associated with the four- and five-equation two-phase models in RETRAN. The four-equation, dynamic slip model is solved by a noniterative method that requires only one evaluation of a single matrix per time step. The five-equation, nonequilibrium model is solved by a two-step method. Calculations show that much larger time steps can be used with the new methods as compared with the standard methods.
