The Air Race E is an event where the success does not lie only in the quality of piloting but in a multitude of factors.
To date, there is no 100% electric racing aircraft. Each of the eight planes that will participate in the race will have been built solely for this purpose. Whether it is the installation of high-performance batteries, a powerful motor or even the pilot interface, everything is new. Crossing the finish line will in itself be an achievement.
At Pie Aeronefs SA, we want to create a high-performance and innovative aircraft. While many competitors are reusing old-generation fuselages and wings by incorporating electrical technology - a process called “retrofit” in the jargon - we decided to create a tailor-made aircraft.
The idea behind this choice is simple, we want to obtain the most efficient aircraft in terms of mechanics and aerodynamics, but also to test new concepts that we can subsequently incorporate into planes available for sale.
Values as of December 28, 2020:
Weight: 373 kg
Length: 4.7 m
Height: 1.50 m
MAC: 0.93 m
Aspect Ratio: 7
VNE : 320 kts
Fixed landing gear - In development
Our EMRAX electric motor is designed to develop 150kW (203HP) during the race. It is mated to a lightweight and sturdy carbon fiber propeller. The propeller is fixed pitch, that is to say that it is not possible to change the angle of the blade according to the speed, as is normally the case on powerful engines.
Weight: 41 kg
Size: 34.8 x 10.7 cm
Max power: 380 kW
Weight: 1 to 3 kg
Diameter: 1.86 m
The aircraft will be equipped with a set of 12 high-performance batteries developed for our aircraft.
Weight: 8 kg
Size: 175 x 675 x 65 mm
Capacity: 1.15 kWh
When a wing flies, it is subjected to different aerodynamic forces. Some consume energy, such as friction with air, and create a force vector called "drag".
There are basically two types of drag to which a wing is subjected: induced and parasitic.
An airplane tail, also called a “tail”, is generally made up of three surfaces: a vertical rudder and two horizontal risers. When using a V-shaped tail, we reduce the number of air contact surfaces. The most striking effect is a noticeable reduction in the induced drag which will allow our plane to go faster.
