003 was strength tested in test bed for ultimate loads according to Czech UL2/2 and Germany LTF requirements:
- Rear fuselage test for ultimate combination loads
- Rear fuselage test for ultimate symmetrical loads
All these loads was created in test bed by sand bags, checked by digital loads measurement. Result - OK, no continuing deformation till max. operational loads. Continuing deformation after 100% of ultimate loads were in “measurement mistake” range - and in fuselage rear cone only. We will increase strength by reinforcing of fuselage rear strength system to 120% for next serial production. In the same time we have aircraft empennages calculated for VD 300 km/hour, to have possibility to increase speeds in next aircraft models.
