SUAVE 2.5.2

This release is a large minor release. The changes are significant but won't change any syntax.

• Multifidelity Rotors
• New aeroacoustic modules
• Fuel tracking and plotting
• Updates for OpenVSP 3.26
• Many many bug fixess

SUAVE 2.5.1

This is a minor release addressing some small bugs.

• Updates to AVL interface
• Addresses issues with negative rudder deflections
• Various OpenVSP import fixes
• Descent Constant EAS Segments

SUAVE 2.5.0

This release has numerous changes. Unfortunately, some interfaces have been altered to support all these changes. We tried to make these interface alterations as user friendly and intuitive as possible.

• VLM: Control surfaces, sideslip, rotation rate effects, and arbitrary discretization.
• Nacelles are now independent geometric objects from networks
• Energy networks: fewer networks, propellers and motors can be appended arbitrarily, networks are no longer referred as propulsors, and integrating a mission with a network is much easier.
• Battery model rewrite
• New airfoil panel method
• Momentum wake effects from rotors
• Updates for both import and export of vehicles to OpenVSP (propellers/rotors are now seamless)
• New Noise models
• Stability derivatives from VLM including with respect to control surface deflections
• VTK file outputs for rotor wake simulations
• New plotting functions
• Under the hood fixes: hover corrections, FLOPS, CG, fineness ratio, propellers/rotors are merged, removed duplicated iterations, addressed many known issues

SUAVE 2.4.0

This release has major changes to both the aerodynamics, acoustics, and propeller models in SUAVE.

• New VORLAX-based supersonic VLM
• Aircraft Noise Analysis
• General VTOL weights buildup
• Electric performance diagrams
• Non-uniform inflow for BET analysis
• Updated propeller-wing interaction
• Direct use of polar data for propellers
• Interface to PyCycle
• Airfoil Interpolator
• New function for supersonic wave drag
• Update OpenVSP interface
• Bug Fixes, code clean up, and some speedups!

SUAVE 2.3.1

SUAVE 2.3.1 builds on 2.3.0 with a few corrections:

• Installation errors when using a local install.
• Propellers no longer default to the NACA 4412 airfoil polars. The default is a curve fit to a DAE51.
• The behavior of the AERODAS post stall model for propellers has been modified to better tracks the original polar.
• Fixes to the optimized climb segment
• Small bug in constant calibrated airspeed segments is fixed

SUAVE 2.3.0

SUAVE 2.3.0 contains a host of upgrades for our users and developers.

*Updates to the native Vortex Lattice Method
*Propeller-wing interaction modeling
*Integrated FLOPS and Raymer aircraft weight estimation methods
*Improvements to eVTOL networks
*New constant-speed Internal Combustion Engine network
*Lift-trimmed single point segments
*Optimized range and endurance speeds for propeller aircraft
*More regressions testing to support our Verification and Validation efforts

SUAVE 2.2.0

SUAVE 2.2.0 brings a wide variety of new capabilities. We suggest all users upgrade to this new version of SUAVE.

• Supersonic Vortex Lattice Method as default aerodynamic method
  -Optimized for quick execution
  -Able to be used with a surrogate or exact throughout a flight
• New Plotting
• Updated weight methods for transport class vehicles
• Differential evolution algorithm with constraints
• New algorithm for CG and Mass computations
• Updated OpenVSP interface
