AFRL completes Ultra LEAP initial flight tests
The Air Force Research Laboratory’s Center for Rapid Innovation has successfully completed initial flight tests for a revolutionary Unmanned Aerial System with a customizable suite of intelligence, surveillance and reconnaissance tools that supports extended missions, AFRL announced December 15.
This series of flight tests began in Feb. 2019 at Dugway Proving Ground, Utah, culminating with a two and a half-day continuous flight demonstration from Dec. 9 to Dec 11. Subsequent flight tests will demonstrate increased levels of flight endurance.
The Ultra Long Endurance Aircraft Platform, or Ultra LEAP, consists of a high-performance, cost-effective, sport-class commercial airframe converted to a fully automated system with autonomous takeoff and landing capabilities. Ultra LEAP also features secure, easy to use navigation employing anti-jam GPS and full global operational access via a satellite-based command and control and high-rate ISR data relay link.
“As the Air Force balances current readiness with long-term modernization, Ultra LEAP represents an affordable approach that supports both existing and future force needs,” said Maj. Gen. William Cooley, AFRL commander, adding that the “enhanced UAS capabilities, along with the cost savings, offers the military a winning solution.”
“Developing a UAS with this level of endurance is an incredible achievement for future warfighting and battlefield success,” said Paul Litke, the AFRL project engineer leading this effort. Litke said since the system employs many commercial off-the-shelf components, Ultra LEAP is expected to dramatically shift the ISR cost-performance curve for the U.S. military.
Developing Ultra LEAP from concept to first flight took less than 10 months, and the system could be ready for operational fielding as soon as 2020. The high level of automation it provides is expected to greatly reduce operator training requirements for the Air Force. Smaller support crews are expected to lead to lower operating costs.
“Accomplished after only 10 months of development by our AFRL industry team, today’s 2 1/2-day Ultra LEAP mission is a significant milestone in solving the tyranny of distance problem for ISR systems,” said Dr. Alok Das, AFRL senior scientist and the CRI director. “It will provide immediate benefit to our warfighters while at the same time paving the path for future low-cost, multi-day endurance ISR systems.”
Ultra LEAP employs many of the subsystems and lessons learned from AFRL’s highly successful prior LEAP program, a UAS that supports missions up to 40 hours. To date, LEAP has completed more than 18,000 combat flight hours and demonstrated one of the lowest mishap rates and smallest mission crew size of any operational UAS in its class. CRI employed the same strategy in both efforts of converting existing aircraft into ISR platforms.
Litke explains by leveraging the commercial aircraft market, AFRL significantly reduced the cost to manufacture and provide logistical spares relative to UAS.
“This way, the U.S. military will save money without sacrificing reliability and maintainability,” he said.
Going forward, parallel AFRL-CRI efforts will focus on UAS operations with short takeoff and landing distances to support deployments at non-traditional locations.
