In this article, Alfred L. Weisbrich, ENECO Texas LLC, USA discusses an alternative wind power technology design, the Wind Amplified Rotor Platform (WARPTM) which uses many identical smaller vertically integrated modules as opposed to one large generator.
The paper presents an analytical framework for addressing the hovering time prediction of rotary-wing aircraft, with a particular focus on multi-rotor platforms.
We demonstrate our results on a small commercially available quad-rotor platform flying in a typical feature-poor indoor environment.
At this year's NAB show, Freefly is returning to the drone market with the Freefly Alta, a ready-to-fly, multi-rotor platform for aerial cinematographers.
A quaternion-based nonlinear control strategy is here presented to steer and keep a generic multi-rotor platform in a given reference position.
This paper presents the black-box modelling and the simulator of a non-commercial hex-rotor platform created completely at the University of Almería, in order to have a tool for teaching control and robotics subjects in industrial engineering and computer science degrees.
The shaft radial run-out signal of a rotor test-platform is applied to simulate the primary noise, and an IIR model identified from a real steel structure is applied to simulate the secondary path.
Its concept is based on designs from the Hiller VZ-1 Pawnee, which was basically a helicopter rotor with a platform on top.
The mechanical vibroactuator is an unbalanced rotor, mounted on the platform and driven with an electric drive.
Template cDNA was amplified with the Rotor-Gene Q platform (Corbet RESEARCH) operating with the Run on Software version "Rotor-Gene 1.7.87".
Then cDNA was obtained using TaqMan® MicroRNA Reverse Transcription Kit (Life Technologies), and qRT-PCR was performed using the TaqMan® MicroRNA Assays in Rotor-Gene Q platform (Qiagen) with TaqMan miRNA assays according to the manufacturer's instructions (Life Technologies).
