FLUID POWER: ThinGap LLC announced a TG14090 Brushless dc Ring Motor that delivers 122 kW of shaft power, allowing a ducted-fan to generate 600 pounds of thrust, depending on the fan blade design. The motor provides an exceptional power to weight ratio—6.4hp per pound; a compact package that fits the control inside the motor and low thermal load characteristics.
The TG14090 design provides a low profile platform that is quiet, cool running, and saves power. By utilizing a cantilever fan blade design, the hub can be designed for either open or closed operation. An open hub provides additional surface area that increases cooling, allowing higher input voltage and shaft output power. A closed hub design fits the control can within the hollow space of the motor for a compact and more aerodynamic package.
Based on physical tests, the operating characteristics of four design configurations for the TG14090 have been calculated. The projections indicated that 70 to 122 kW of continuous shaft output power is possible. This allows a TG14090 configuration, weighing 25.6 lbs. and producing shaft output of 163hp, to deliver 6.4hp per pound of motor weight.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
A recent example of a major CAE revamp is MSC Apex, released last month by MSC Software Corp. In a discussion with Design News, MSC executives noted that its next-generation platform is designed to substantially reduce CAE modeling and process time, “in some cases from weeks down to hours.”
The Thames Deckway would run for eight miles close to the river’s edge, rising and falling slightly with the tidal cycle. It will generate its own energy from a series of devices that will line the pathway and use a combination of sources to make the path self-sustaining.
