The airframe is completely made of composite material which excels in its specific strength and excellent fatigue properties. The entire aircraft can be broken down into individual units, i. e., both halves of the wing and tail surfaces, including stabilizers, can be separated from the fuselage to ease aircraft transport.
The aerodynamic design of the wing gives the aircraft appropriate fall characteristics. The separation of air flow in the critical angle of slope happens at the root of the wing. This ensures good handling of the machine until it drops and symmetrically stalls. This allows for the aircraft’s smooth and agile handling.
The tail section employs a true and tested traditional design. The internal structure of the stabilizers is similar to the construction of the wings. Therefore the tail section can be completely removed from the hull, with the exception of the keel, which is its integral part.
The VL3 is certified and tested in collaboration with the Czech Aerospace Institute. The VL3 was successfully tested to ultimate loads up to +15G’s and -8G’s.
Regarding flutter the VL3 is free of it until 460 km/h. However due to our rescue system (parachute) our VNE is limited to 305 km/h. The rescue system can be activated until 305 km/h. Nevertheless the VL3 was tested in flight at much higher speeds.
The maximum speed in gusts is limited to 235 km/h because safety is our priority. At 235 km/h IAS we have still a safety margin of 300%. That means that if you will fly at 235 km/h IAS in a gust of +15 m/s you will stress the plane with +5G’s. As we have ultimate loading of +15G’s you have a huge safety margin. Our philosophy is to protect the pilot as much as possible by applying general aviation safety coefficients of 2,25 at least.
To increase safety the VL3 can be equipped with a TCAS (Traffic alert and Collision Avoidance). When an other traffic will be in your vicinity you will receive a visual and audio alert to your EFIS and headset.
Also an ELT ( Emergency locator transmitter) can be installed in case of emergency landing SAR services will find you quickly.
The parachute system is designed to protect occupants in the event of an emergency by lowering the aircraft to the ground after deployment.
In the event of an in-flight emergency, pulling the red handle deploys a solid-fuel rocket out a hatch that covers the compartment where the parachute is stored.
As the rocket carries the parachute rearward from the front of the aircraft, the embedded airplane harness straps release from the fuselage.
