Scaled Composites Unveils and Tests Model 401 – a New Experimental Aircraft

Last Wednesday, Northrop Grumman subsidiary Scaled Composites has unveiled and flown the first of two new experimental aircraft called the Model 401. Scaled worked with a proprietary customer to build two vehicles to demonstrate advanced, low-cost manufacturing techniques and to provide aircraft for research flight services to industry partners and the United States government. This successful first flight is the beginning of the flight test phase for vehicle number 1.

The two vehicles were designed to be identical in outer mold line and performance, with each aircraft powered by a single Pratt & Whitney JTD-15D-5D engine with 3,045 pounds of thrust. The vehicles are capable of flying Mach 0.6 with a service ceiling of 30,000 feet and have a wingspan of 38 feet and are 38 feet long. They have an empty weight of 4,000 pounds and a maximum take-off weight of 8,000 pounds with an endurance of up to three hours.

Aaron Cassebeer, Project Engineer said, “This is such an exciting time for us. Scaled is at the forefront of experimental aircraft development and I am fortunate enough to have a front row seat.” He went on to say this about the mission, “[Wednesday] was a great day for our test team. We had a great flight and we are looking forward to the future test program.”

Scaled Composites is one of the premier leaders in aerospace composite manufacturing. The company is also currently developing the Stratolaunch, the world’s largest aircraft. Scaled is also responsible for Virgin Galactic’s all-carbon composite SpaceShipTwo, known as VSS Unity, and its mothership, the WhiteKnightTwo.

The Scaled team plans to continue envelope expansion on the first Model 401 aircraft as they move toward first flight of the second vehicle.
