Entry Systems and Vehicle Development Branch Code TSS

Antonella Alunni Branch Chief | Code TSS

Entry Systems and Vehicle Development Branch NASA Ames Research Center

Overview

• TSS was established in 2009 to work with discipline-oriented branches (TSA, TSM, TSF) and provide a leadership approach for sub-system design and hardware components that comprise entry systems.

• Currently, branch comprises 11 civil servants and 11 contractors.

- 19 NASA Honor Awards in Exceptional Service (2), Achievement

(2), Engineering Achievement (5), Early Career Achievement (5), and Outstanding Leadership (5).

• In the last decade, TSS has built up core competencies that enable the branch to deliver end-to-end entry systems and vehicle development capabilities.

Management of Disciplines

Development & Delivery of Flight HW

4You’ll see a healthy mix of these competencies highlighted in the projects we support

- Lead and deputy EDL systems engineers: Development of EDL requirements, interface oversight, EDL V&V

- Support roles for TPS, capsule dynamics, avionics, parachute descent system, and DrEAM (Dragonfly Entry Aerosciences Measurements) SE

• Anticipated Future Work

- Arcjet test support and data analysis

- Additional V&V support for EDL Assembly

- Support for DrEAM instrumentation development, system testing, and V&V

- Entry reconstruction after landing

• Growth Areas:

- Additional lead roles on future Class A missions

- Mission proposal and implementation with APL as partner

Support for early phase proposals can lead to high ROI with significant roles on prominent missions 5

• TSS Disciplines engaged are TPS, As-flown and Entry

Instrumentation, System Level Testing, System Analysis, Project Management

• Follow On Work and Growth Areas

• FTPS and Instrumentation Investigations, Integrated System Test

Support, & Flight Test Support

• Team uncovered many instrumentation issues/unknowns.

Investigations underway & additional forward work is being scoped to address these subjects.

• LOFTID is a stepwise development & test approach for a ~11m HIAD to be used by ULA & other interested commercial partners. ARC will be deeply integrated in development of the ~11m structure at both aeroshell vendors.

• HIAD is currently the leader for the hypersonic phase of Humans to Mars. Many instrumentation & aeroshell development tasks will be required to reach Mars-scale entry vehicle.

Orion TPS Insight / Oversight

• Phase D/E Orion TPS Insight / Oversight at Ames

- Performs oversight of the overall Lockheed Martin Orion TPS effort

(analysis, design, build, & flight)

- Plans and executes the Orion arc jet test program

- Plans and executes Heat Shield Post-flight inspection, sampling, and analysis

- Oversees and approves verification closures in support of Artemis 1

- Collaboration with TSA, TSM, TSF, AA, RE, and JAI

• Key Roles in TSS

- Orion TPS Deputy System Manager, Post-Flight Lead, and ~half of the post-flight team

- TSS disciplines engaged are Project Management, TPS, System

Level Testing, and As-flown and Entry Instrumentation

• Incoming work, growth areas, mission infusion potential, or follow-on work

- Exposure to ATLO and operations support is providing growth opportunities § Class A hardware hands-on work for post-flight § Tight coordination with the Orion Program, Exploration Ground Systems

(EGS), and Lockheed Martin

- Post-flight work is ground-breaking and could be applied to other

Earth entry vehicle evaluations, both in and outside of NASA § Sampling and inspection techniques § CT-based density measurements 7

Artemis 1 Heat Shield Scan Support

Avcoat sampling

Artemis 1 Recovery Support

MEDLI2

• MEDLI2 is the entry instrumentation suite on Mars 2020

- MEDLI2 project is collaboration with LaRC and JPL.

- MEDLI2 project has been funded through STMD (GCD), HEOMD (AES), & SMD (MPO).

- At Ames, collaboration is with TSA, TSM, TSF, and QS.

• MEDLI2 Roles and Support in TSS

- TSS Provides Leadership and Key Technical Roles:

§ MEDLI2 Principal Investigator and former deputy Project Manager.

§ Responsibility and expertise for transforming flight temperature measurements into high-value sources for future Entry vehicle design.

- TSS played extensive role in sensor development, testing, and

“Do No Harm” acceptance on flagship-class mission.

- TSS (and TSM) leadership key to successful Ames 2019

QAAR (Quality Audit, Assessment, and Review) featuring MEDLI2.

• Ongoing and Follow-on Work for MEDLI2

- Continued Reconstruction of MSL & M2020 Flight Data funded through Entry

Systems Modeling (FY21-FY23).

- Feed forward into MSR Sample Retrieval Lander (SRL) Mission Design.

- Feed forward into next generation of EDL Instrumentation

§ MEDLI3 for MSR SRL, DrEAMS on Dragonfly, § Entry Instrumentation evaluation required on all future SMD Discovery and NF proposals.

• Our advocacy of EDL instrumentation has led to the SMD requirement that all vehicles entering an atmosphere must carry instrumentation.

MSR EES

Mars Sample Return Earth Entry System

• Phase B MSR EES at Ames

- End-to-end analysis, design, and test support at the EES level

- Provides flight TPS hardware

- Collaboration with TSA, TSM, TSF, RE, JAI, QS

• Key Roles in TSS

- Nearly all TSS disciplines are engaged, providing the core EES leadership at Ames

• TSS EES support showcases the ‘whole-mission’ capabilities of TSS

- Past experience on Orion, MSL, M2020, & the HEEET Project has created a strong cross-discipline capability in the branch for applied

EDL

- The experience of bringing HEEET to TRL 6 is enabling for seeing 3MDCP through to flight

- EES experience positions the branch to learn and extend into broader mission leadership and support moving forward

- Success with EES demonstrates that continued growth and investment in ‘whole mission’ support is a priority, benefitting the entire division

ADEPT

Adaptable, Deployable Entry and Placement Technology

ADEPT

• Started under 2010 NASA-funded study and later became an Ames-led STMD project since 2012

• TSS led and supported prototyping, ground testing, sub-orbital flight test (SR-1) that matured ADEPT to TRL 5 and demonstrated major technological benefits:

- Overcoming entry vehicle packaging and volume constraints in LV shroud or as secondary payload

- Deployed configuration achieves low ballistic coefficient (m/CdA), reducing peak heating and dynamic pressure loads

- Woven carbon fabric tested up to 250 W/cm2

• Supported JPL on drag modulated aerocapture (DMA) development to modulate time of ADEPT drag skirt jettison and enable targeting to a specified orbit

• We’ve also partnered with JPL’s DMA team for a proposed Technology Demonstration Mission Earth flight test for SmallSat class missions

Summary

• TSS is key to the success of many of NASA’s entry technologies and missions

- Since 2009 inception, Branch has built up strong experience in systems, hardware, flight projects

- TSS staff is cross-trained and has strong leadership in high-profile

NASA missions § Holding major entry vehicle technical and programmatic roles § Best representation in Entry Systems for Ames since Galileo

• The future for TSS is to:

- Provide continued leadership in Entry Systems at Ames and across the agency,

- Continue to expand our experience within our core competencies.
