Adaptation to other Airframes:
The DYNAMIC 450 Wing can be adapted for use on other airframes (trike base) than those
manufactured by DTA SARL (a limited liability company) subject to the compliance with the
following points:
•
The Maximum Take-Off Weight of the wing is observed (including wing weight).
•
the engine power rating is at least 37 kW minimum required for safe two-seater flight.
•
The flight tests are progressive and MUST be carried out SOLO, in stable conditions
and without wind, on a large/long runway with ample emergency egress.
This will
make it safer to adapt the wing to the trike-body.
•
Complete wing and keel clearance is essential, both in pitch and roll, “Control Bar full back”
and “Control Bar full forward”.
•
The minimum safe distance from the propeller arc to the wing keel, from the lower
rear longitudinal cables and at the trailing edge of the wing MUST be at least 10 cm,
this MUST factor all possible wing positions and include flight positions.
•
In flight - position of the control bar at cruise speed with maximum loading: at least 20 cm
from the belly of the pilot in fast flight, and 30 cm from the front strut in slow flight. in hang
bracket position n°2 (CF section 3 – 03).
Note: The person/s who choose/s to use a non-DTA airframe will assume ALL the responsibilities
related to the adaptation for the non-DTA airframe to the DTA wing as well as the flight testing
.
Attention: poorly mounted powerful engines, the fitting of badly dimensioned or badly
positioned fairing can cause interaction between the wing and the airframe which can cause
the flight behaviour of the aircraft to change abruptly and render it uncontrollable.
