    The smart active blade tip (SABT) rotor is an on-blade rotor vibration reduction system, incorporating active blade tips that can be independently pitched with respect to the main blade. The active blade tip rotor development included an experimental test program culminating in a Mach scale hover test, and a parallel development of a coupled, elastic actuator and rotor blade analysis for Cited by: 9.

Therefore, a hover study was conducted using rotor systems for which the only difference was airfoil shape. This hover test used a small-scale, four-bladed rotor model with two tapered rotors. sertation explores the design issues that affect the hover performance of small-scale. rotors and the implementation of a working coaxial MAV prototype. A computerized hover test stand was used for the systematic testing of single. and coaxial small-scale rotors.

SyntaxTextGen not activatedThe small-scale rotor hover pdf was performed in the test section of the NASA Ames by Foot Wind Tunnel. Use of the large tunnel test section as a hover chamber has several advantages. First, the environment is easily controlled, obviating the need to .aerodynamic performance of rotor aircrafts (Nixon et al., ), e.g.

bending–twist coupling and extension–twist coupling. The small-scale rotors on Micro Air Vehicles (MAVs) also suffer the problem caused by different blade twist rates between hover and forward flight (Shkarayev et al., ).Ebook of Results. A hover test was conducted on ebook small-scale model using three tapered rotor systems and a baseline rectangular-planform rotor system.

The tapered­ blade planforms had taper initiating at 50, 75, and 94 percent of the blade radius with a taper ratio of 3 to 1 for each blade set.
