Release Actuator Employing Components With Different Coefficients Of Thermal Expansion

US Patent:
2013005, Mar 7, 2013
Filed:
Aug 16, 2012
Appl. No.:
13/587150
Inventors:
Clint T. Apland - Elkridge MD, US
David R. Weir - Hanover PA, US
David F. Persons - Columbia MD, US
Michael T. Marley - Elkridge MD, US
Assignee:
THE JOHNS HOPKINS UNIVERSITY - Baltimore MD
International Classification:
F03G 7/06
US Classification:
60528, 60527, 60529
Abstract:
An actuator includes a capturing part, a retained part and a heating element which applies heat to the retained part or the capturing part responsive to selective application of power to the at least one heating element. The capturing part attaches to a first object and has a first coefficient of thermal expansion. The retained part attaches to a second object and has a second coefficient of thermal expansion. The retained part is insertable into the capturing part in a first state of the actuator. The retained part is held in contact with the capturing part via an interference fit to hold the first and second objects proximate to each other in a second state. The retained part is ejected from the capturing part in a third state. Applying heat via the heating element causes a transition between the second and the first or third states of the actuator.

Adaptor System For Deploying Small Satellites

US Patent:
2014013, May 15, 2014
Filed:
May 6, 2013
Appl. No.:
13/887423
Inventors:
The Johns Hopkins University - , US
Aaron Q. Rogers - Silver Spring MD, US
David F. Persons - Columbia MD, US
Robert A. Summers - Dayton MD, US
Assignee:
The Johns Hopkins University - Baltimore MD
International Classification:
B64G 1/64
US Classification:
2441733
Abstract:
An adaptor system includes a space vehicle separation plate operably coupled to a space vehicle, a launch vehicle adaptor plate operably coupled to a launch vehicle capable of carrying the space vehicle into space for release of the space vehicle from the launch vehicle, an actuator release mechanism assembly, a bend/shear restrain assembly that is non-coaxial with the actuator-release connector, and a biasing element. The actuator-release mechanism assembly may be configured to separably couple the space vehicle separation plate to the launch vehicle adaptor plate. The actuator-release actuator-release mechanism assembly may pass through the launch vehicle adaptor plate to engage the space vehicle separation plate to hold the space vehicle separation plate substantially parallel to the launch vehicle adaptor plate prior to release of the space vehicle separation plate.
