AMDROHP
January 2022
AMDROHP has completed its final mechanical review, and stock is being purchased for part fabrication to begin the first integrated thermal prototype. JPL has successfully printed a full scale prototype of the entire radiator system, complete with springs, an evaporator plate, and a condenser plate. Integration of the full scale prototype with the CubeSat chassis has been planned along with the environmental testing of the complete prototype.
November 2021
The AMDROHP successfully submitted to NASA’s CubeSat Launch Initiative (CSLI) with a letter of funding commitment for that phase. The thermal prototype is on track to be manufactured and delivered next quarter, on time. The JPL/CSULA Teams have successfully printed some prototype units of the spring joints and the radiator plates. Experimental testing has been completed on the prototype spring joints, demonstrating their ability to undergo loading stresses while deployed.

AMDROHP is approaching thermal prototype readiness; starting the end of this quarter/beginning of next quarter, they will be manufacturing the thermal prototype bus. On the payload side, JPL and CSLA will be 3D printing a prototype of the payload and integrating it with the bus. Following this, the vehicle will be testing in TVAC and experiments with the payload will be run to compare with the thermal simulations predicting on-orbit behavior. On the deployment side, Cal Poly has developed a new mechanism and plans to try to test it with a separate prototype before the quarter is out.
February 28th 2021:
Much of the recent focus of the AMDROHP team has been towards developing a deployment mechanism for the radiator panel payload. Different designs and latches are being considered as the project continues towards a defined radiator design in collaboration with Cal State LA and NASA JPL.
February 1, 2021:
In January AMDROHP concluded reviewing results from the Preliminary Design Review and begun the next phase of the project. On the radiator side by JPL and CSLA, work continues developing the radiator and the flexible joints. On the side of the spacecraft bus by the Cal Poly CubeSat Laboratory, work is ramping up with the development of the deployment mechanism for the radiator and sensor selection/integration. There continues to be development in defining the methods by which the temperature gradient of the radiator will be determined on-orbit and predicting the behavior of the temperature sensors and the data they record, along with the margins for error.
November 3, 2020:
The AMDROHP team primarily worked on mission planning in the month of October. The development of the radiator to integrate into the CubeSat bus continues to progress.
October 7th 2020:
The AMDROHP team is focusing on the integration of the radiator into a CubeSat design, as well as expanding the project within the CubeSat Laboratory to the full range of disciplines. This involves work such as developing the deployable mechanism for the radiator and designing the stowed configuration to support the radiator during launch. Additionally, the AMDROHP team has created a larger systems engineering infrastructure to support the efficacy of the multi-disciplinary group involved as well as the continuity of the project moving forward.
August–September 2020:
AMDROHP is a new project in collaboration with NASA JPL and Cal State LA to design an Additively Manufactured Deployable Radiator with Oscillating Heat Pipes (AMDROHP) and an accompanying CubeSat mission. The project is still in the early stages of technology and concept development.
