ThunderStruck Images and Animation.

It has been a long time coming as there are only so many hours in the day. The images and our ability to do 3D renditions and even 3D printing is courtesy of Ben Hockley from Brisbane, Australia.

Ben has created this fantastic image of the Phase one Thunderstruck craft. It is pictured just after going subsonic and making the transition to horizontal flight. At this point it will be slowing to about 500kph and is about to slowly deploy the canards. These are little wings at the front of the craft. Unlike the wings, the canards will have lift and will be set to work with a nose down angle of about 10 degrees. Tests will determine whether we will need to change the angle for landing or whether the canards will remain in line with the fuselage at all times during the flight. I suspect the later will be the correct arrangement and much easier to build, but testing is always required.

Thunderstruck1Why not a slender body? Simply we will achieve supersonic speeds due to lack of air. Well very “thin” air. A tiny fraction of 1% at sea level. Drag is not the issue here until we are in level subsonic flight. There we will be taking a step glide path anyway as there is no lift in the wings. I will be happy with a 10 to 1 glide slope. We lose a metre for every 10m flown. The drag on the body will not be the greatest issue and I would like the body big enough to add the Patch antennas. They stick on the outside of the craft and I will want that to be on top of the body and under the body so that there is signal no mater what the orientation of the craft. The added benefit is that we have plenty of room to work on the electronics, servos and other gadgets that need to move within the body of the craft. The diameter of the craft at full scale will be about 600mm in diameter. This may change with flight testing, but we are now in the final stages of the paper design and the engineering of the mechanical components will all fit comfortably in this size craft.


The drawings were done with Solidworks and you can, if you are a student, pick up a copy for US$150 and since this is Jason’s project and he is a year 8 student, he qualifies. The images at right are the craft’s plans and the top right shows a view of the craft, including the lines differentiating the sections used to create the fuselage. ie the nose cone joins the first half of the fuselage. These lines are removed for rendering a coloured and textured model as seen in the top image.

Although we do not yet have animation of the flight, it can now be produced with the 3D files that come from the rendering process. These are STL files and moving the background and the view of the craft (angle of attack), vibration, etc, can give the required feel of flight. The files will be sent to an animator to see if this can easily be achieved. If yes, we hope to have the animation ready to show you and also use it in the ever so essential crowd funding video. The three images above are shown below. All are courtesy of Ben Hockley and the picture with clouds in the background is courtesy of NASA and taken from the International Space Station (ISS). Ben thanks again for these fantastic ThunderStruck images.
