IMLM
(Integrated Motor Life Management) In-House:
Validation of A&S modeling capability AFNWC funded supported for ANDES improvement (Automated NDE Data Evaluation System) The WOWs Potential to provide millions in cost avoidance Provide accurate, near-real-time motor health condition (diagnostics) Provide individualized service life estimates (prognostics) Transition opportunity ~ 2018 Goals: Reduce predictive uncertainty of future state of a motor on an individual basis by 20%/50% (near/far term goals) Analysis Command & control
Initial state and inspection data Data processing and storage Sensors to include:
temperature, humidity, case damage, propellant slump, acceleration, and TVA displacement and load First integration of motor specific sensor data to advanced aging models to provide a individualized service life estimate
MCAT
(Motor Component Assessment Technology) What are we doing? Developing new solid rocket motor (SRM) components and M&S tools that decrease inert weight by 20%.
Customer why? High-speed penetrator weapons will enable attack of deeply-buried targets.
Tech Reason? New M&S tools may show possibility of higher efficiencies from SRM designs.
Transition? 3 of 6 FY12 task orders support an AFRL FCC. 1 of 6 FY12 task orders supports AFNWC.
In-House:
Experiments to validate new models The WOWs The AFNWC propellant task is part of a plan that may save $2.1B in future acquisition costs.
We are only gov’t lab doing solid rocket motor R&D for launch & strategic needs.
USET
(Upper Stage Engine Technology Program) Validating new suite of LOx/Hydrogen rocket engine M&S tools through heavily-instrumented 4,000 hp, 90,000 rpm turbopump Risk reduction work ups TRL of components allowing SMC/LR NGE program to enter post-milestone B, saving years on the schedule and $multi-M’s in cost Verify and Validate suite of tools to greatly reduce the amount of physical testing by conducting better M&S during design NGE with SMC/LR and tools used in current NGE risk reduction work, Hydrocarbon Boost, >45 M&S tool-specific transitions to industry, DOD, NASA
In-House:
Test stand Buildup Design of new facility hardware Hardware Fabrication Hardware Installation In-house tool validation and verification On-site rapid data reduction and analysis
The WOWs:
SMC/LR requested TTP transition to NGE Key member of AUSEP (Affordable Upper Stage Engine Program) IPT Conducted Risk Reduction work on USET contract to support AUSEP TRL requirements Most highly instrumented, highest tip speed and suction of any turbopump ever tested
SMC/LR AUSEP Vision Engine
Program Completed, Report in Progress
HC Boost (Hydrocarbon Boost Program)
In-House:
Building subscale test facility to mitigate combustion devices risk Critical combustion research using 219 funds Fuel thermal stability, nozzle cooling, injector design The WOWs:
Design, build, test ORSC LOx/Kerosene Liquid Rocket Engine Tech Demonstrator 250K-lbf with high Throttle Capability (SOTA is 2:1) – Enables mission flexibility 100 Life Cycle with 50 cycle overhaul (SOTA is 20) – Exceeds requirement, provides margin ORSC is a higher performing engine resulting in a smaller launch vehicle or an increase in delivered payload
HCB establishes advanced, modern, domestic LRE Tech Base Required to replace Russian RD-180 on EELV U.S.’s 1st reusable, high-perf HC engine Establishes Ox-rich staged combustion (ORSC) tech base for U.S.
Sustain ailing U.S. rocket engine industry tech development base HCB strongly supports SMC/LR American Kerosene Engine project
Electric Propulsion What are we doing? Developing new technologies that enable less expensive, more maneuverable and more agile s/c Customer Why? Reducing launch mass substantially reduces launch cost, increases payload fraction, and enables missions otherwise not possible (e.g. AEHF) Tech Reason? Plasma propulsion increases Isp by 10x, reducing s/c propellant 10x, enabling lighter and/or more capable s/c Transition?
Test facilities 8 vacuum chambers Thruster design Diagnostics Validation of M&S Mod/Sim Program Advanced numerical methods
The WOWs:
AEHF requested assistance with thruster performance verification; SV-2 onboard diagnostics package flying Developed propulsion module for FalconSat-5 tech demo, including spacecraft interaction diagnostics Cubesat EP propulsion module selected by 2 constellations for flight in 2014 National M&S effort for EP coordinated by AFRL-RZSS
AEHF SV2 Sensor Package
Tech demos: FalconSat-5–demonstrating low power propulsion and spacecraft impact Operational systems: AEHF–enabling high mass spacecraft directly supporting warfighter
AFRL Developed Advanced Monopropellants What are we doing? Providing advanced propellant with higher performance and much lower toxicity than hydrazine Customer why? Faster operational response with reduced costs can be attained with greater mission capabilities Tech Reason? Energetic ionic liquids provide low vapor toxicity and high energy density Transition? Orbital flight experiment on TBD S/C-2014
Small Spacecraft Benefits Trade Analysis 1N – 12N N2H4 Thrusters
NTO/MMH Bipropropellant AFRL Advanced Monopropellant Hydrazine Monopropellant
Advanced monoprops can perform like bipropellant in small craft!
Fully characterized small scale safety & hazard properties Passes all safety requirements DOT approval for transport First successful thruster firings Pilot scale propellant production Advanced monopropellant cost = hydrazine cost Supplying transition programs
What Have We Done Lately?
Recent Technical Achievements Transitioned 200W Hall Thruster to TacSat-2 Delivered 8 CubeSat thrusters to NRO (10x inc in performance USET demo (liquid rocket engine turbopump), M&S transitions & tech transition to customer Hydrocarbon Boost subscale preburner on test stand (testing to begin CY14) Combustion Stability Test Rig/Facility passed last hurdled, testing to begin this quarter (219 funded) New energetic ingredient (furazan class) cleared for large batch (10 lb) scale-up
