Their Defiant X design is predicated on the SB-1 Defiant, the same although smaller expertise demonstrator. In June, the SB-1 recorded a prime velocity of 235 miles per hour, already a lot quicker than typical helicopter speeds. Based on a SB-1 check pilot, the SB-1 used lower than 50 p.c of engine output to achieve that velocity, indicating that the bigger and sure extra highly effective Defiant X might attain even greater speeds.
The SB-1 provided a number of benefits over the venerable Black Hawk helicopter it want to substitute. Although it has the identical footprint because the Black Hawk, it has about double the helicopter’s prime velocity and vary, and because of its contrarotating composite rotors, is probably going extra maneuverable. SB-1 engineers have additionally touted the SB-1’s capability to fly decrease to the bottom and at greater velocity than most helicopters can, a capability that might assist the Defiant X keep away from enemy radar.
Although the brand new Defiant X and its father or mother SB-1 airframe share many visible similarities, spokespeople at Boeing and Lockheed Martin have acknowledged that the Defiant X options enhancements to its aerodynamics and a decreased thermal signature.
