Boeing and JAXA to flight-test technology to improve safety

Theodore Koumelis - 07 August 2017, 00:09

The JAXA LIDAR technology offers the potential to accurately measure winds as much as 17.5 kilometers in front of airplanes and provide pilots with sufficient time to take appropriate action to avoid wind shear and clear air turbulence, which does not have any visual cues such as clouds.

SEATTLE - Boeing and the Japan Aerospace Exploration Agency(JAXA) will flight-test Long-range Light Detection and Ranging (LIDAR) technology next year. This remote-sensing technology could help commercial airplane pilots better detect and avoid weather disturbances to improve flight safety.

Boeing and JAXA have been collaborating on the integration of LIDAR technology into a commercial airplane platform since 2010. The JAXA LIDAR technology offers the potential to accurately measure winds as much as 17.5 kilometers in front of airplanes and provide pilots with sufficient time to take appropriate action to avoid wind shear and clear air turbulence, which does not have any visual cues such as clouds.

"Boeing is very pleased with the collaborative relationship we have had with JAXA," said Naveed Hussain, Boeing Research & Technology vice president, Aeromechanics Technology. "We look forward to demonstrating the benefits of LIDAR technology, which offers significant opportunities for aircraft safety and performance."

This next phase of the JAXA-Boeing LIDAR research collaboration is possible thanks to Boeing's ecoDemonstrator flight-test research program. In 2018, Boeing and FedEx Express will work together for six weeks to flight-test more than 30 technologies including LIDAR aboard a new FedEx-owned 777 Freighter. FedEx and Boeing are committed to reducing the environmental impact of their products and advancing technology that will improve performance.

"Boeing's ecoDemonstrator flight-test programs accelerate innovation that enhances the safety and efficiency of commercial flight," said Doug Christensen, ecoDemonstrator program manager. "We're eager to continue working with JAXA so that we can both learn more about LIDAR technology."

The flight demonstration of LIDAR technology will involve emitting pulses of laser light, which will scatter off of small dust and other particulates. Observing the reflected light in segments from the start, the pulse provides measurement of the wind speed at increments all along the direction of the laser.

"We are very pleased to take part in Boeing's ecoDemonstrator program. The onboard clear-air turbulence detection system to be tested in the program next year was established by JAXA as part of our SafeAvio R&D project on avionics safety technology to prevent turbulence-induced aircraft accidents," said Fumikazu Itoh, director general, JAXA Aeronautical Technology Directorate. "Boeing's ecoDemonstrator program provides us with valuable opportunity to evaluate our system's capability on large commercial aircraft, which will help accelerate practical implementation of our system in a real environment."

Since 2012, the ecoDemonstrator program has used a series of flying testbeds to develop and test aviation technologies that enhance safety and environmental performance. The Boeing ecoDemonstrator program plays a key role in the company's environmental strategy by using flight testing to accelerate new technologies that can reduce emissions and noise, improve airlines' gate-to-gate efficiency and help meet other environmental goals.
