Introduction to UAV

The NASA IKHANA UAS Platform

Ikhana History

Vision:

NASA’s Predator-B is a rapidly reconfigurable test system that

develops and demonstrates advanced HALE technologies leading to ROA applications that improve life here.

In the Native American Choctaw language, the word Ikhana means intelligent, conscious, or aware. This made it the perfect word to represent the aircraft NASA has selected to demonstrate technologies seeking to make unpiloted aircraft more intelligent and autonomous. In FY05, NASA initiated the procurement of a Predator-B aircraft (fig. 1 and 2) with a plan to host the flight demonstration of these advanced autonomy technologies, namely: Intelligent Mission Management (IMM) and Integrated Vehicle System Management (IVSM). The demonstrated reliability of the Predator-B allowed experimenters to focus on research instead of the platform and permit FAA-approved operations in the National Airspace (NAS).

Operations Concept

Chase aircraft required below 18k in the U.S. National Airspace (NAS)

Air traffic control (ATC) used for collision avoidance above 18,000 ft

NASA Dryden uses restricted airspace to climb to cruise altitude before exiting into the NAS

Since Ikhana not qualified for Reduced Vertical Separation Minima (RVSM), operations are limited to 18,000 ft to 29,000 ft or above 41,000 ft

Transponder and radio communication required

Fiber Optic Wing Shape Sensors (FOWSS)

Ikhana Fiber Optic Wing Shape Sensors (FOWSS) Project

In June 2003, the Helios Prototype unpiloted aerial vehicle (UAV) experienced significant pitch instability during low-altitude flight that lead to a catastrophic structural failure and in-flight break-up. One of the most significant lessons learned from the mishap investigation was the requirement to provide real-time measurement of wing shape. It was decided that lightweight and low profile fiber optic wing shape sensors (FOWSS), in conjunction with computationally efficient algorithms, was a promising approach to providing very accurate wing measurement calculations for eventual input to the flight control system for aero elastic motion control. FO channel covered for So. CA firestorm missions (Oct. 2007)
