March, 2012: LG-1000 Full-Scale Prototype Successfully Flight Tested
Success! The Logistic Gliders team flew a full scale LG-1000 prototype and demonstrated stable flight, adequate structural margin and a sufficient glide ratio to carry cargo 70 nautical miles when dropped from an operational altitude. The prototype was designed and built using only $600 in materials – less than 1/3 of the cost of nylon used in today’s cargo parafoils.
The glider was towed aloft using a 100 ft cargo line attached to a Hiller utility helicopter, and released at approximately 1,400 ft above the ground at 48 knots airspeed. A low-altitude helicopter release allowed the ground team to view the flight characteristics of the glider while safely under tow. The low release velocity was chosen to eliminate any risk to the helicopter after glider deployment. Direct radio control was used in lieu of the Airborne Guidance Unit (AGU) since the prototype was not equipped with a braking parachute.
The prototype was equipped with two cameras and two Data Acquisition Systems (DAS). A MUVI DV camcorder was installed on top of the left vertical stabilizer, and HD FlipCam camera was installed under the port wing looking outward toward the wing tip. An Eagle Tree DAS recorded airspeed, altitude and control servo positions. An Arduino-based GPS telemetry system provided LAT/LONG, altitude, heading, and groundspeed data. All telemetry data was stored to a memory card and wirelessly transmitted to a ground-based laptop via a 900 MHZ spread spectrum XBee-PRO XSC RF Modules. Flight control was provided by a digital 72 MHz radio control (RC) system designed for model airplanes. All cameras and DAS survived the landing. A two minute video of the March 2012 test including clips from on-board cameras and from a ground camera equipped with a telephoto lens can be seen here.
July, 2011: Logistic Gliders Signs CRADA with Natick Soldier Center, MA
Logistic Gliders is excited to announce it has fully executed a Collaborative Research And Development Agreement (CRADA) with the Natick Soldier Research, Development and Engineering Center (NSRDEC) in Natick, Massachusetts. CRADAs will allow both parties to collaborate on the planning, execution and post-processing of data for flight tests of the LG-1000.
“The CRADA is the first step towards enhanced collaboration with NSRDEC. We at Logistic Gliders were very excited when NSRDEC presented us with this opportunity”. - William Russell, Logistic Gliders
