SHARPy Simulations of the SuperFlexop

This repository contains scripts to simulate the nonlinear aeroelastic gust response of the (Super)Flexop with SHARPy, and to generate a linearized version (plus optional reduced-order model) of this aircraft model.

Both, the nonlinear aeroelastic simulation environment SHARPy and the SHARPy version of the (Super)Flexop model are included in this repository as submodules.

Installation

Clone the repository to your local computer. Navigate into the sharpy folder

cd <path-to-repository>/lib/sharpy

and install SHARPy as described in the documentation.

Alternatively, you can use a SHARPy distribution that is already installed on your machine. The SHARPy version used must be at least v2.0.

Running Simulations

First, activate SHARPy's conda environment and append the location of the flexop-model folder to the system's path with

source <path-to-flexop-model>/bin/FLEXOP_vars.sh

Now, the user should be all set to either run a nonlinear aeroelastic gust response study of the (Super)Flexop with

python <path-to-repository>/run_nonlinear_simulation.py

or generate a linear full-order order reduced-order model of this model with

python <path-to-repository>/generate_linear_system.py

Note that both scripts contain several parameters to be specified by the user.

Postprocessors

An example postprocessor script is added to the repo. This script exports displacement and rotation of the tip node as well as the wing root bending and torsional moments computed for each timestep of a gust response simulation saved under a given case name.
