The L-39NG passed the aerodynamic tests for armed version

press release

Shortly after the L-39NG training version certification, an important initial step in the preparation of its armed version has been completed. A series of L-39NG tests took place in the low-speed wind tunnel of the Czech Aerospace Research Centre in Prague (VZLU), this time the tests were focused on the ability of the aircraft to carry various weapon systems.

"In cooperation with the VZLU, we have completed the data collection phase from the wind tunnel before the aircraft will be converted to the armed version and before the flight tests will begin next year. Our goal was to experimentally verify the expected deviations of aerodynamic performance that might be different from the training version," said the head of the L-39NG program Vojtěch Labuda from Aero Vodochody. For the needs of measurement, a model of the aircraft was 3D printed using the scale of 1:6.6. The model was subsequently measured using six-component internal strain gauge balance in a low-speed wind tunnel (wind tunnel measuring space has a diameter of three meters).

At first, measurements on the aircraft without pods took place, and then the aircraft with different types of pods, weapons, flap settings and different types of wing ends was measured. All weapon models were also made by 3D printing.

The L-39NG aircraft has five pods for carrying a wide range of weapons, starting with a machine gun calibre 12.7 millimetres or cannons calibre 20 millimetres, bombs up to 250 kilograms, unguided air-to-ground missiles or air-to-air missiles. The integration of laser guidance of weapons is also in consideration.

Before the flight tests, it was necessary to verify the effect on flight characteristics and performance by tests in the wind tunnel. During the measurements, the influence of the angle of attack and the angle of sideslip on the aerodynamic characteristics of the aircraft with different variants of weapons and settings of the flaps was investigated.

In addition to static measurements, which determine the forces and momentum strengths on the aircraft, dynamic measurements were also performed. This determines the aerodynamic damping for the flying qualities purposes.

"In a half a year, we have performed more than 200 measurements, in 30 different configurations, from a clean aircraft to a fully equipped aircraft with tilted flaps. During these measurements, it turned out that the aerodynamic model is fully capable of carrying a wide range of weapons in various configurations," said Pavel Hospodář from VZLU. The measured data will be used for calculations of flight performance.


eVTOL: XERI Awarded New Halo Aircraft Patent


Press release


BOCA RATON, FL / ACCESSWIRE / November 18, 2020 / Xeriant, Inc. (OTC PINK:XERI), a new aerospace technology holding company, announced today that an additional utility patent has been issued by the U.S. Patent and Trademark Office related to its Halo aircraft technology, strengthening its October 2019 patent. Both utility patents are retroactive to Halo's original 2007 continuation patent application date, and therefore have the benefit of preceding numerous drone or UAV (unmanned aerial vehicle) patent filings and claims.

Halo is a development-stage eVTOL (electric vertical takeoff and landing) powered lift aircraft that has been designed to seamlessly transition from vertical to forward flight by altering the direction of its propulsive thrust by approximately 90 degrees. Powered lift aircraft combine the VTOL capability and small logistical footprint of helicopters with the cruise speed, fuel efficiency and range of conventional fixed wing airplanes. Halo's unique and scalable tiltwing configuration, which features a pivoting cylindrical wing structure and a central axle-mounted payload area, can also accommodate a range of propulsion systems, including ducted lift fans and distributed electric rotors, as well as various stability and control systems.

When fully developed, Xeriant plans to introduce the innovative Halo platform as a small high-performance UAV for commercial applications such as inspections, surveying, surveillance, delivery and imagery, which is expected to compete favorably with other eVTOL UAV aircraft in terms of speed, acoustics, payload, maneuverability, efficiency, range and safety. Depending on the success of the small UAV model, Xeriant may begin to develop a larger scale Halo aircraft model for the emerging UAM (urban air mobility) market or a variant for military applications. UAM, which is part of advanced air mobility, refers to on-demand passenger or cargo transport in congested environments.

Halo was chosen to be a finalist presenter, out of approximately 70 companies, at the November 2019 Florida Aerospace Capital Forum.

"UAVs represent one of the most dynamic growth sectors in aerospace, with applications expanding into almost every industry. Empowered by innovation, these new aerial vehicles promise to make aviation a greater part of our daily lives. The additional patent protection on the Halo technology supports our efforts to establish a strong position in this space," stated Xeriant CEO, Keith Duffy.
