Functional limitations

Trial version of RPA Standard Edition v.2.0 has the following functional limitations in thermal analysis module:

  • fixed number of stations distributed along the thrust chamber is equal to 30
  • maximum number of cooling sections is limited to 3

After you complete the payment, you will receive notification with your personalized product key and the link to the password-protected page where you can download the fully functional version of RPA without any limitations.

Installation instructions

See User Manual: Installation.

Note: RPA for Windows depends on MS VC++ 2008 SP1 runtime libraries. If your computer does not have it installed, please choose the installer that includes all required components, or download and install redistributable runtime components from Microsoft download center: for x86 (download size 4.0 MB); for x64 (download size 4.7 MB).

Note: in order to install RPA for Windows from installation executable file you must have administrator rights. If you don't have administrative rights, you can still install the program from ZIP package.

Change Log

RPA Standard Edition v.2.0.0.1

  • fixed mistake that under specific circumstances could cause a program to hang while calculating the engine altitude performance.
  • fixed mistake that caused the program crash when loading old project configuration file (v.1.x) and trying to switch to thermal analysis screen (demo version only is affected).

RPA Standard Edition v.2.0.0

  • Calculation of heat transfer rate distribution (convection and radiation) with or without boundary layer coolant
  • Film cooling analysis
  • Radiation cooling analysis
  • Regenerative cooling analysis:
    • coaxial shell jacket
    • tubular wall jacket
    • jacket with milled channels
  • Thermal analysis of thrust chambers with combined cooling (radiation + film + regenerative)
  • Estimation of hydraulic loss in the cooling passages
  • Estimation of friction thrust loss
  • Estimation of divergence thrust loss for nozzle with truncated ideal nozzle contour (TIC)

RPA Standard Edition v.1.2.6.4

  • fixed mistake in scripting utility rpas that caused program crash due to memory leak
  • distribution packages include Qt v.4.8.0
  • added two options into command line utility rpac:
    • -pr, or --performance prints out the performance tables at the end of standard output
    • -pt N, or --points N defines the number of lines N in altitude performance table; only effective together with the option -pr

RPA Standard Edition v.1.2.6.3 & RPA Lite Edition v.1.2.5.2

  • fixed mistake in definition of nozzle exit condition in throttled performance analysis
  • fixed mistake in calculation of thrust in throttled performance analysis
  • improved thrust level discretization in throttled performance analysis
  • improved pressure discretization in altitude performance analysis

RPA v.1.2.6.2

Standard Edition
  • improved algorithm for calculation of sonic velocity at nozzle throat section for reaction products with condensed phase
  • added user manual in PDF format

RPA v.1.2.6.1

Standard Edition
  • mistake that makes impossible the modifying the fuel mass fraction on screen "Propellant Specification" is fixed

RPA v.1.2.6

Standard Edition
  • calculation of additional nozzle stations
  • calculated thrust is added to altitude performance table
  • calculated thrust (at SL, opt and vac conditions) is added to throttled performance table
  • in both Nested Analysis and Propellant Analysis tools, any of calculated parameters (Is, Tc, c*, Cf) can be plotted on diagram "parameter vs. O/F ratio"
  • improved calculation of estimated delivered performance

See complete change log.
