held by internal tabs in the casing. On one side, there are
the components in charge of telemetry and on the other
side those in charge of photogrammetry. Finally, a 30
angle sectional cut, with a central hole, was made where
the camera is positioned so that it has good area coverage.
This cut extends both to the casing and to one of the bays
for aesthetic reasons.
The design of the bays was made deployable for a
more practical handling for the connection of the batteries,
these are attached to the housing by means oftabs. Finally,
the cover is adapted to the design of the other parts, which
allows the joint of the structure by means of two screws,
and has two holes through which the transmitting antenna
passes and a ring through which the parachute is tied.
Due to the requirements imposed and the specifications
mentioned, it was decided to manufacture the parts
in 3D printing made of PLA, this material was chosen
because it met the needs of the project and was available
from our sponsor Cipsela Corporation.
LAUNCH AND RECOVERY
To accomplish the Nikola Tesla mission, a vehicle is
required to carry the CanSat to its maximum altitude, and
also is needed a mechanism to safely recover IRVI when
it is landing in free fall. According to the functions to be
performed by the CanSat, the launch and recovery procedures
were decided.
LAUNCHING
The launch vehicle that will carry the CanSat to an altitude
ofmore than 1000 m will be a drone. This flight-controlled
device allows us to perform the trajectory corresponding
to the ascent. It consists of raising the picosatellite to the
appropriate height, turn with it in a straight profile so that
it can take pictures at apogee, let it drop it to activate the
recovery system and in this way, both can reach the
34
ground safely, as it is illustrated in Figure 10. Additionally,
the drone does not interfere with the telemetry transmission
and preserves the integrity and positioning of the
different components inside the structure.
Tests carried out using a four-propeller drone, showed
that the system works correctly, both in transmitting and
sending data to the ground station and taking photographs.
RECOVERY
The safe return of the CanSat is something critical to the
mission, as well as a requirement for the competition, so a
stable, slow, and controlled descent was considered for
proper payload performance. Several types of parachutes
and paragliders were considered. However, the final
choice was a circular parachute that was designed according
to the required parameters.
