The X.2 Limited Flight Test Plan is for the CycloCrane Program. The principal objectives of the planned tests are to (1) assess a number of ground handling scenarios for the X.2 system to determine the preferred mix of Ground Support Equipment (GSE) and personnel for efficient and safe field operations, and (2) obtain specific performance data needed to support design development; e.g., hover power of new, four engine configuration. The aerostat has a diameter of 68 feet and is 136 feet long. The fabric is a polyurethane coated dacron. The X.2 CycloCrane is powered by four Hirth F-30 (110 horsepower each) two-stroke engines. The total weight of these four engines with reduction belt drives and exhaust manifolds is 440 pounds. The four propellers are wooden, three-bladed fixed pitch with a diameter of 92 inches. The telemetry subsystem has been upgraded to accommodate the installation of four engines place of the original two. It has a truly remote control operation and is relatively simple but reliable.
