The pelican.xml file is not configured properly to launch in Gazebo. I've managed a quick fix that you can use. You must add and tags to the xml file so that Gazebo can provide the correct physics to the model. I've also added tags to specify physics parameters and colors. I've included an example from my modified file. You can further modify it to improve upon it later, particularly the model dynamics and physics. I hope that this helps.
