Lighter Than Air

Lighter Than Air (LTA) is an aerospace research and development company which isthat manufacturingmanufactures experimental and certified airships, for both mannedcrewed and unmanneduncrewed flight. The company is focused on developing the technology and capability of airships while also lowering the cost to make airships useful in modern applications. This includes applications such as humanitarian aid delivery, disaster response and relief efforts, and reduced carbon emissions for flight, while making use of the airshipsairship's ability to reach remote areas whichthat cannot otherwise be accessed by plane or boat due to limited or destroyed infrastructure.

LTA was founded in 2015 by Google co-foundercofounder Sergey Brin with the opening of a research and development lab in Mountain View, California, and a second hangar opened in Akron, Ohio opened, in 2016.

The company developed a debut prototype, the Pathfinder 1, which was 120 meters long and 40 meters wide at its widest, with a dozen propellers and laser sensors, described as making the blimps seenblimp's advertising at NFL games seem nothing more than inflated bags with minimal gondolas struckstuck underneath. TheAccording to reports, the airship was, according to reports, able to lift 28 tons, cruise at speeds up to 110 kilometers per hour, and offer a range of more than 4,500 kilometers.

LTA has said the development of the airship has looked at using new and different materials, to make them safe to fly, and maintain their strength and low weight. This has included using carbon fiber reinforcedfiber-reinforced polymer tubes with titanium joints in the frame and 3D girders while using non-flammable helium as a lifting gas. LTA Research is also developing a second prototype, the Pathfinder 3, intended to 180 meters long.

The Pathfinder 1 uses twelve electric propeller motors, which line the sides and tail of the airship, and are capable of rotating +180 to -180 degressdegrees for directional control. The motors are controlled by a fly-by-wire system, which combines pilot commands with sensor feedback to direct the motors and four fin rudders to fly the airship. And the airship uses Lidar sensors to accurately and continuously calculate the volume of helium in the gas cells to maintain flight safety, while the outer-coveringouter covering of the airship is a laminated Tedlar material, which has shown to be lightweight, strong, non-flammable, and UV-resistant.
