Performance of a Closed Cycle Power Takeoff for a Shore-Based Wave Energy Device

A promising class of devices for ocean wave energy conversion is called the oscillating water column in which power transferred to an airflow that rotates a turbine. closed cycle takeoff (CCPTO), air forced through two valves and turbine, has main benefits such system: it allows

Short Takeoff Performance using Circulation Control

Historically, powered lift takeoff analysis has been prohibitively expensive for use in preliminary design. For powered lift, the coupling of aircraft systems invalidates traditional simplistic methods often used in early aircraft sizing. This research creates a tool that will au

Propulsion System Modeling and Takeoff Distance Calculations for a Powered-Lift Aircraft with Circulation-Control Wing Aerodynamics

The computation of takeoff distance for powered-lift aircraft is complicated because of the coupling of aerodynamic performance (lift, drag and moment coefficients) with forward speed. Cal Poly has developed an analysis procedure to capture this coupling, and the development of t

Heavy Payload Tethered Hexaroters for Agricultural Applications: Power Supply Design

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract This research paper addresses the design problem of heavy payload tethered hexarotor for agricultural applications where payload re

Thermal fatigue and failure of electronic power device substrates

Electronic power devices used for transportation applications (automotive and avionics) experience severe temperature variations, which promote their thermal fatigue and failure. For example, for power modules mounted on the engine of an aircraft, temperature variations range fro

Perching and takeoff of a robotic insect on overhangs using switchable electrostatic adhesion.

For aerial robots, maintaining a high vantage point for an extended time is crucial in many applications. However, available on-board power and mechanical fatigue constrain their flight time, especially for smaller, battery-powered aircraft. Perching on elevated structures is a b
