Loads Correlation of a Full-Scale Proprotor on the Tiltrotor Test Rig [PDF]
In 2018, a full-scale isolated proprotor test was conducted in the USAF National Full-Scale Aerodynamics Complex (NFAC) at NASA Ames. The test article was the 3-bladed Bell 699 research rotor derived from the AW609 rotor.

Viking Orbiter 1975 thrust vector control system accuracy [PDF]
The thrust vector control (TVC) system of the Viking Orbiter 1975 is discussed. The purpose of the TVC system is to point the engine thrust at the vehicle center of mass and to maintain attitude stability during propulsive maneuvers. This is accomplished

Weighing at sea with a gimbal platform
, 1970 Abstract : The use of a gimbal platform with two degrees of freedom under dampened pendulum motion allows a standard laboratory balance to be used to weigh scientific samples at sea. The maximum sample weight tested was approximately 120 grams, while the average accuracy obtained in samples ranging from 1 to 120 grams was 0.10% (plus or minus .05 ...
