The model is named Samaras Suppliers after the samara seed: like a maple seed, it has wings, and while free-falling it rotates - which slows the descent and helps it land safely, decreasing the impact velocity.
How it protects the payload
- The attached propeller rotates during landing, decreasing the landing impact.
- The front spherical object absorbs much of the force and translates the stress wave through the meshed, optimised shell.
- An extra container is included to act as an insulator, keeping the chamber at the optimal temperature for drugs or chemicals.
- A hook is attached so the container can be dropped with a parachute from great height.
The whole model is built around that same samara principle.
Optimisation
One of the parts is optimised using a generative design technique in Solid Edge. After generating roughly a 50% reduction in mass, the overall part was simulated for a 48 lb load (including dead weight).
What the attachment can carry
- Delicate instruments
- Blood
