Near term plan

@milanofthe, @agodemar here is my thinking in terms of a near term plan for pathsim-flight.

First off, the following blocks have been committed to the repo.

• ISAAtmosphere
• JSBSimWrapper
• Airspeed Conversions
  • CAStoMach
  • MachToCAS
  • CAStoTAS
  • TAStoCAS
  • CAStoEAS
  • EAStoTAS

The following have been implemented locally, just need to create test cases.

• DynamicPressure
• IncidenceSideslipAirspeed
• CrossProduct
• AngleConversion

The following are busy being developed.

• Multiply (with matrix option)
• DCMs
• 6DOF (Euler Angles)

The idea being in terms of an 'initial' release that would allow us to demo some basic aircraft modeling via both the JSBSimWrapper block as well as by using 'basic' pathsim-flight blocks as you would typically do via Simulink.

Example snippets of Simulink models for basic aircraft modelling.

In terms of an initial example aircraft model I was planning on making use of the Research Civil Aircraft Model (RCAM). So creating a JSBSim version of the RCAM and then build a pathsim-flight basic blocks version of the RCAM.

See Christoper Lum's videos on the RCAM.

Building a Matlab/Simulink Model of an Aircraft: The Research Civil Aircraft Model (RCAM)

Once that is done then I would look to expand the set of available blocks in pathsim-flight to roughly match the set of blocks available in Matlab/Simulink's Aerospace Blockset.

This issue is a broad roadmap for pathsim-flight, covering blocks such as DynamicPressure, IncidenceSideslipAirspeed, CrossProduct, AngleConversion, Multiply, DCMs, and 6DOF. Start by reviewing the existing implementations and tests for these blocks, then clarify which single block or RCAM example is in scope. Done should mean that the selected feature is implemented, tested, and demonstrated in a working aircraft model.
