July 31, 2013 - A new option for performing aerobatics is among the new products on display at EAA AirVenture Oshkosh, Rud Aero's two-place RA-3.
An all-carbon aerobatic machine, the RA-3 is the logical follow-on to the RA-2 that Rud unveiled here last year.
The RA-3 also differs from most aerobatic machines with side-by-side instead of tandem seating.
Rud, of Sebastian, Florida, optimized the RA-3 design for primary flight training as well as comfortable economical cross-country flight, maintaining fully aerobatic qualities in a traveling machine.
Founded in 2011, Rud Aero's goal is to build a new generation of lighter, stronger, less-expensive aircraft made entirely of carbon fiber. The company is named for its owner, Taras Rud of the Ukraine.
Rud's first effort at building world-class aerobatic aircraft resulted in the RA-2, an Unlimited class aerobatic airplane, specifically designed for world-class aerobatic pilot Sergei Boriak. The two-seat tandem RA-2, according to Rud Aero, exceeds the capabilities of all existing aerobatic aircraft.
Its lightweight carbon fiber airframe is the strongest in its class, able to sustain +/-13g's with a two-times safety factor. The RA-2 is a built-to-order airplane for world-class aerobatic pilots.
The RA-3-like the RA-2 before it-offers interchangeable wing options: one for beginner/intermediate aerobatics, the other for advanced aerobatics.
In this way it is possible to first train on a cambered training wing, then convert to a constant chord symmetrical wing for advanced aerobatics.
The RA-3's rugged, lightweight carbon fiber airframe is rated for Â±8g with a two-times safety factor.
The RA-3 is intended to be certified in the primary category under FAR Part 21.24. A similar, but lighter airplane, designated the RA-3 LSA-now in the pipeline-will be certified as an LSA and will have a useful load of more than 500 pounds.
Rud Aero's facilities include full composite capabilities and five-axis CNC router capabilities, allowing the company to fabricate most of the composite and metal parts in-house. Final assembly is done in a 17,000-square-foot hangar on the Sebastian Municipal Airport.
The core of the prototyping and production team is composed of engineers drawn from the talent pool at nearby Kennedy Space Center.
The company has a 35,000-square-foot production facility and a 25,000-square foot assembly building in Sebastian. Production tooling will be fabricated using a state-of-the-art Par 5-axis milling machine, and composite parts will be made in climate-controlled rooms. The process allows parts to be built much more precisely and quickly.
