Questo è il primo concept di Athena, successivamente rimpiazzato con un modello più leggero e resistente.

Nella parte bassa vediamo una parte stampata in 3D che contribuisce ad apportare stabilità (grazie alle fins) e al contempo a dare la possibilità di avere delle clamps.

In version 2.0 the strength and weight are improved, which are acharacteristics necessary in a similar context.

The lower part has also been improved, which now implements a perfect fit with the launchpad clamps.

Sections have been opened to allow access to the on-board computers and a possible video recording or ejection of lateral parachutes, without however influencing the aerodynamic characteristics too much.

The height changes slightly. Now it allows more passive stability and more space for the parachute.

This is the very first version of the TVC developed, later replaced by V2.0 following mechanical errors due to:

• poor smoothness

• low total extension

• precarious stiffness

• unjustified printing difficulties

Once again iterative design demonstrates how malfunction learning processes can benefit the final design.

Version 2.0 compared to the first develops:

• greater smoothness

• ease and speed of printing

• greater stiffness

• low weight

• captivating aesthetics

Thanks to Yukon Aereospace for supporting this development and providing advices.

This PCB board, now in its fourth iteration, is the beating heart of the stabilization and data recording system.
