The Brazilian company Novaer acted as the actual designer and manufacturer of the B-250, and Brazilian aircraft designer Josef, formerly the main creator of the well-known successful turboprop aircraft of the same class Embraer EMB-312 Tucano and EMB-314 Super Tucano, was the main designer.
“The B-250 is one-piece and has a slightly larger size than the Tucano and Super Tucano, and, unlike the latter, is positioned precisely as a light combat attack aircraft (primarily counterinsurgency) with the use of reconnaissance and surveillance as an aircraft. Possible educational functions are considered as secondary, ”the article says.
The length of the aircraft - 10,98 m, wingspan - 12,08 m. The machine has a double cabin with tandem crew accommodation in ejection seats.
It is reported that “the B-250 is powered by a Pratt & Whitney Canada PT6A-68 turboprop with a takeoff power of 1600 hp. with a four-bladed Hartzell propeller, a Rockwell Collins ProLine Fusion avionics complex, and a ventral round-the-clock optoelectronic station. " The total mass of the outboard weapons is up to 3960 pounds (1796 kg).
The prototype was demonstrated at Dubai Airshow 2017 with "guided bombs with satellite correction by the UAE company Tawazun Dynamics, South Korean 70-mm corrected LIG Nex1 LOGIR missiles with an infrared guidance system and DS-16 compact guided munitions."
According to the developers, “the distillation distance of the B-250 is 2400 miles (4445 km); flight duration - up to 12 hours; maximum speed 301 knot (557 km / h); practical ceiling over 30 thousands of feet. Operating costs are less than $ 1200 per flight hour. "
