SCREEN DATABASE DEVELOPMENT FOR THE INFLUENTIAL FACTORS OF LIQUID ACQUISITION DEVICE SCREENS THE PROPOSED RESEARCH WILL ADVANCE TECHNOLOGY AREA (TA) 2.4.2.3 IN-SPACE TANK-TO-TANK PROPELLANT TRANSFER BY CARRYING OUT A SUITE OF EXPERIMENTS AND MODEL DEVELOPMENT ON SCREEN CHANNEL LIQUID ACQUISITION DEVICES (LADS). SCREEN CHANNEL LADS ARE A TECHNOLOGY INSTALLED INSIDE AN IN-SPACE STORAGE TANK THAT ARE ABLE TO SEPARATE THE LIQUID PHASE FROM THE VAPOR PHASE BY USING THE LIQUID S SURFACE TENSION. IN THIS WAY THEY ENABLE THE TRANSFER OF PURE LIQUID CRYOGENIC PROPELLANT IN REDUCED GRAVITY. SCREEN CHANNEL LADS CAN DELIVER SINGLE-PHASE LIQUID AT HIGHER FLOW RATES THAN OTHER LAD TYPES AND ARE ABLE TO MAINTAIN PHASE SEPARATION DURING UNPREDICTABLE ACCELERATIONS WHICH ARE EXPECTED CONDITIONS FOR INTERPLANETARY TRANSIT VEHICLES PROPELLANT DEPOTS AND SATELLITE SERVICING VEHICLES. THERE ARE SEVERAL UNSOLVED PROBLEMS PERTAINING TO THE HYDRODYNAMICS HEAT TRANSFER AND PHASE CHANGE OF CRYOGENIC FLOW THROUGH SCREEN CHANNEL LADS. SINCE THE SCALE OF THE IN-SPACE CRYOGENIC SYSTEMS IS PROJECTED TO BE MUCH LARGER AND OPERATE AT MUCH HIGHER FLOW RATES THAN ANY PREVIOUSLY MADE STORABLE PROPELLANT SYSTEM IT IS ESSENTIAL FOR FUTURE MANNED SPACE EXPLORATION MISSIONS THAT THE PERFORMANCE OF SCREEN CHANNEL LADS CAN BE PREDICTED WITH HIGH ACCURACY. THE MODEL EQUATIONS DEVELOPED FROM THIS PROJECT WILL ENABLE THE ACCURATE PREDICTION OF SCREEN CHANNEL LAD PERFORMANCE. THE PROPOSED PROJECT DURATION IS TWO YEARS. THE FIRST YEAR WILL BE DEVOTED TO TESTING AND EXPERIMENTATION USING ROOM TEMPERATURE LIQUIDS WHILE THE SECOND YEAR LIQUID CRYOGENS WILL BE THE WORKING FLUIDS. THE BULK OF THE MODEL DEVELOPMENT WILL BE COMPLETED IN THE FIRST YEAR. DURING THE SECOND YEAR VERIFICATION AND VALIDATION OF THE MODEL WILL BE PERFORMED.
