May 5th to 11th, 2007: Autonomous Airplane Perch Tests - Part 1

In these flight tests, a fixed vertical landing platform was designed and attached to a concrete pole in the middle of the RAVEN flight space to allow the fixed-wing aircraft to land and perch on the pole. This test is similar to the test performed on January 28th, 2007 except in this test the platform was attached to the wall. This test was repeated number of times and a video shows repeating the vehicle take-off, hover and land sequence twice.


April 12th, 2007: Autonomous Airplane Level Flight Testing

In this flight test, the aircraft took off from the vertical landing apparatus and autonomously moved to a location in the northeastern area of the room in the hover configuration. Once the vehicle reached this location, the vehicle was commanded to transition to level flight mode and flew 3 laps around the room. These three laps were completed in about 10 secs (since the vehicle was flying at approx. 6 m/s during the flight). Following the laps, the system commanded the vehicle to transition back to the hover mode and once it stablized itself began its decent to attempt a landing on the vertical landing apparatus. Note that room is approx 8 meters wide.


February 28th, 2007: Autonomous Airplane Transition (Hover-Level Flight-Hover) Tests

In these flight tests, the operator moved the airplane to a location in the room and the system commanded the vehicle to transition to level flight mode and back to hover mode. This test was done as a precursor to the level flight testing. This transistion capability allows the system to autonomously commande the airplane to a level flight state from a hover (and vise versa). Note that these transistions take less than 2 seconds to complete and both transitions were completed in less than 20 ft (7 m).


February 26th, 2007: Autonomous Airplane Ground Take-off to Hover

In these flight tests, the airplane was setup in the conventional level flight state and the system commanded the vehicle to take-off to a hover. This ground takeoff to hover conversion occurs in under 25 ft (8 m).


January 28th, 2007: Autonomous Airplane Perch Tests - Part 1

In these flight tests, a portable vertical landing platform was designed and setup in the middle of the RAVEN flight space to allow the fixed-wing aircraft to land and perch on the platform. This test was repeated number of times and this video shows the vehicle landing, taking off, hovering and landing again.


October 2006: First Autonomous Airplane Hover Tests

The purpose of these flight test was to demonstrate the system's capability to autonomously control a fixed-wing aircraft in a prophang. This was the first time in our laboratory that a fixed-wing aircraft was flown in this configuration. Many subsequent tests were performed in addition to this test.


July 25th to July 31st, 2006: Airplane Tracking Test Flights

As part of our architecture upgrade tests, we had a pilot fly an airplane in our testbed's flight area to see if we could track and display the vehicle's position and orientation using the testbed's 3D visual interface display. During this testing we demonstrate the system's capability to acquire the position of an airplane flown by a pilot and display the data using the platform's 3D interface.
