Publication number: 20130221580Abstract: The present application relates to a method and system that can be utilized to manufacturing composite structures in a closed cavity mold. The tool system includes a closed cavity tool with spring members that when in compression apply pressure to a preform located within the closed cavity mold. During a curing cycle, the spring members provide substantially constant pressure to the preform, thereby preventing voids and porosity in the cured composite structure. Further, the substantially constant pressure, provided by the spring members, acts to more effectively conform the preform to the geometry defined by a void in the closed cavity mold during the curing cycle.Type: ApplicationFiled: February 24, 2012Publication date: August 29, 2013Applicant: BELL HELICOPTER TEXTRON INC.Inventors: Stephen K.

Publication number: 20130221153Abstract: The system is configured for automation of rotorcraft entry into autorotation. The system can provide a means to assist the flight crew of a rotorcraft in maintaining rotor speed following loss of engine power. The system can automatically adjust control positions, actuator positions or both to prevent excessive loss of rotor speed upon initial loss of engine power before the flight crew is able to react. The system uses model matching to provide axis decoupling and yaw anticipation; it includes pitch control initially to assist in preventing rotor deceleration; and it makes use of collective, pitch, roll and yaw trim functions to provide tactile cueing to the pilot to assist when the pilot is in the loop. The system can reduce workload by assisting the crew with controlling rotor speed and forward speed during stabilized autorotation.Type: ApplicationFiled: February 14, 2013Publication date: August 29, 2013Applicant: BELL HELICOPTER TEXTRON INC.Inventor: BELL HELICOPTER TEXTRON INC.

Patent number: 8521384Abstract: A turf maintenance vehicle all-wheel drive traction control system includes a primary wheel propelling the vehicle. A first motor rotates the primary wheel. A traction control system has a first portion communicating with the first motor to monitor either a first motor current demand or a rotational speed of the primary wheel or the first motor and generates a traction control value. A secondary wheel rotated by a second motor steers the vehicle in a vehicle non-slip condition. A traction control system second portion determines a secondary wheel steering angle value. A speed threshold limit stored in the traction control system compared to the traction control value generates a slippage occurrence message indicative of a primary wheel traction loss event. A second motor drive signal created by comparing the steering angle value and the slippage occurrence message energizes the second motor during the traction loss event.Type: GrantFiled: January 27, 2009Date of Patent: August 27, 2013Assignee: Textron Innovations Inc.Inventors: Sean C.
