Embraer tests the Vmu of E190-E2 (Video)
Sao Paulo - Embraer performed an exciting test earlier this month with one of the prototypes of the new jet E190-E2, the model baptized as "Ozires Silva", named after the founder of the company.
The test was performed at the installation of the group in Gavião Peixoto (SP). The aim of the test was to determine the minimum take-off speed (Vmu) of the aircraft.
In this test, the airplane accelerates down the runway until it reaches its maximum safe AOA (Angle of Attack) before taking off. The tail of the aircraft comes into contact with the runway and, according to the manufacturer, the airspeed is measured exactly when it takes off.
To protect the tail and the fuselage from the damage, the test aircraft was equipped with a device acting as a safety barrier between the fuselage and the runway, when the aircraft reaches the maximum AOA during the take-off procedure at minimum speed.
Embraer explains that Vmu tests help determine the critical take-off speeds and the minimum distance required for the aircraft to take off.
The test aircraft has demonstrated exceptional handling characteristics in the AOA and is extremely controllable even at low speeds,the manufacturer said.
The E190-E2 is the most advanced commercial aircraft ever developed in Brazil, with full fly-by-wire and low-consumption engines.
The first flight of the new generation model was carried out in May 2016. The development and certification program, which involves several tests, such as lightning and ice resistance, and wet run tests, is being run with four prototypes.
As announced by Embraer, the first E190-E2 is scheduled to be delivered in April 2018. The launch customer of the new Brazilian jet is Norway's regional operator Widerøe.
Embraer has more than 80 orders in his order book for the E190-E2.
