1-g Suit Port Concept Evaluator 2008 Test Results

2009-07-12
2009-01-2572
The Lunar Electric Rover (LER), which was formerly called the Small Pressurized Rover (SPR), is currently being carried as an integral part of the lunar surface architectures that are under consideration in the Constellation Program. One element of the LER is the suit port, which is the means by which crew members perform Extravehicular Activities (EVAs). Two suit port deliverables were produced in fiscal year 2008: a 1-g suit port concept evaluator for functional integrated testing with the LER 1-g concept vehicle and a functional and pressurizable Engineering Unit (EU). This paper focuses on the 1-g suit port concept evaluator test results from the Desert Research and Technology Studies (D-RATS) October 2008 testing at Black Point Lava Flow (BPLF), Arizona. The 1-g suit port concept evaluator was integrated with the 1-g LER cabin and chassis concepts.

AS5652
This SAE Aerospace Standard (AS) contains requirements for a digital time division command/response multiplex data bus, for use in systems integration that is functionally similar to MIL-STD-1553B with Notice 2 but with a star topology and some deleted functionality. ...Even with the use of this document, differences may exist between multiplex data buses in different system applications due to particular application requirements and the options allowed in this document. ...Even with the use of this document, differences may exist between multiplex data buses in different system applications due to particular application requirements and the options allowed in this document. The system designer must recognize this fact and design the multiplex bus controller (BC) hardware and software to accommodate such differences.

13-Conductor Electrical Cable between Towing Vehicle and Trailer

2022-06-15
WIP
J3284
This SAE standard establishes the minimum construction and performance requirements for a combination cable consisting of 9 conductors and 2 twisted pairs for use on trucks, trailers, and dollies. The cable includes power, ground and 2 jacketed/unshielded twisted paired signal circuits. This standard will be used in conjunction with the SAEJ XXXX “13 Conductor Electrical Connector (Plug and Receptacle) between Towing Vehicle and Trailer”. The standard will also include the test procedures, design and performance requirements for the cable.

135 Days in Isolation and Confinement: The Hubes Simulation

1995-07-01
951512
The EUROMIR-95 flight was selected as model for the HUBES experiment: a similar duration (135 days), a similar crew (3 men), similar schedule organisation (8 hours work, 8 hours sleep, 8 hours off-duties), similar workload for the crew and the mission control (performance of scientific experiments), similar setup for communication and data processing, and similar layout of the MIR station, as the simulation was performed in the MIR simulator located at the Institute for BioMedical Problems (IBMP) in Moscow. The Scientific Programme of HUBES had been elaborated by integration of 31 experiments from more than 80 research proposals from Principal Investigators from Europe, USA and Russia, in domains of Physiology, Psychology, Operations and Technology.

1500 W Deployable Radiator with Loop Heat Pipe

2001-07-09
2001-01-2194
Two-phase capillary loops are being extensively studied as heat collection and rejection systems for space applications as they appear to satisfy several requirements like low weight, low volume, temperature control under variable heat loads and/or heat sink, operation under on ground and micro gravity conditions, simplicity of mounting and heat transfer through tortuous paths. ...When developing new Deployable Radiator the designs of the following key components were engineered and tested: - High-power Loop Heat Pipe evaporator with low weight and extremely low thermal resistance; - Pressure regulator for passive thermal stabilization of payload; - Loop Heat Pipe serial/parallel condenser that allows multiple freezing of the working fluid; de-freezing system; - Thermal key that allows the Radiator multiple opening and closing without application of the explosive means (without shock loads).
