FASTER Engineering Model

During the development of the FASTER EM we had the opportunity to have at our

disposal a Tecnam P92, which is one of the most popular ULA (Ultra Light Aircraft) in

Italy. It is a single-engine high-wing aircraft which employs a monocoque tail cone

section with the forward fuselage using sheet aluminum over steel tubing [Ref. (46)].

After a careful inspection of the P92, the most suitable solution found was to fix an

external POD, containing the camera, to the lower structure of the plane in the passenger

door area, using a c-shaped bracket. This configuration allows also to pass all the

necessary cable (power, usb and camera shooting) through the door, to reach the internal

computing and management unit placed behind the two seats. The c-shaped bracket is

made of folded aluminum, 5 mm thick to prevent door misalignment once it is closed and

it is blocked to the airplane structure using two threaded bolt. Being very close to the

engine mount, especially at high rpm, vibrations may have adverse effects on image

quality (blur) so an insulating neoprene adhesive has been placed between the fuselage

and the supporting bracket.

The bracket is then attached to a wood base on which is mounted the EOS camera

through the plastic adaptor, described in section 5.1.3. 4 small silent blocks are placed

between the plastic adaptor and the wood base. For security reasons iron wire is used as

an emergency retain system in case of failure.

In order to protect the camera from relative wind and possible impacts during

landing, an aerodynamic canopy has been designed and realized. For this purpose the

three-dimensional model of the EOS camera, including also the plastic adapter and silent

blocks, was used to identify a reference volume that has to be covered by the canopy and

the final shape has been founded using a spline interpolation of 6 points.
