This, when coupled with NASA’s aging workforce (the average age as of 2016 was 49), stresses the importance of capturing knowledge to pass along to the next generation of NASA engineers. <\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>The Structures, Loads and Dynamics, Mechanical Systems, and Materials (SLAMMS) disciplines have also been identified as critical fields for the advancement of NASA\u2019s strategic vision, which emphasizes the importance of developing and retaining engineers in those areas. Consequently, the SLAM(M)S Steering Committee (Materials was not initially included), comprising center SLAMS Division\/Branch Chiefs and NASA Technical Fellows, formed the Young Professionals Forum in 2012, which evolved into the current Early Career Forum (ECF) in 2017, and was expanded to provide year-round activities (e.g., monthly meetings, training opportunities) for the Early Career Community (ECC). <\/p>\n\n\n\n<p><\/p>\n\n\n\n<p> Over the lifetime of the ECC, the SLAMS Steering Committee was dissolved, and the stewardship of the ECC relied on the Technical Fellows, who empowered ECC leaders to take on the primary responsibility of planning and running the ECC and ECF events. <\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>Today\u2019s SLAMMS Early Career Community   <\/strong><\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>Within the past few years, a new SLAMMS Division\/Branch Chief collaboration group was formed, called the SLAMMS Leadership Working Group (LWG), and is led by James  Loughlin, GSFC Mechanical Systems Division Chief, with co-lead Elonso Rayos, JSC Structures Engineering Assistant Division Chief. The LWG is a forum focused on capability sustainment, discipline technical challenges, and workforce concerns. For example, disparate Agency technical resource access is discussed, collaboration is coordinated, and critical gaps in expertise are filled using cross-Agency cooperation. <\/p>\n\n\n\n<p>The current SLAMMS ECE leadership team includes Khadijah Shariff (JSC-Structures), Dr. Matthew Chamberlain (LaRC- Loads & Dynamics), Dr. Jonathan Sauder (JPL-Mechanical Systems), and Cassie Smith (JPL-Mechanical Systems). NASA Technical Fellows supporting SLAMMS are Deneen Taylor (Structures), Dr. Dexter Johnson (Loads & Dynamics), Dr. Michael Dube (Mechanical Systems), and Dr. Bryan McEnerney (Materials).<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>The SLAMMS Early Career Forum<\/strong><\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>The ECF is the annual \u201cface-to-face\u201d workshop for the community. The ECF is held at a different NASA center each year and features technical presentations by early career engineers (ECE), splinter sessions with NASA Technical Fellows, mentor presentations, facility tours, networking events, design challenges, and evening social activities to advance the SLAMMS disciplines and develop NASA\u2019s future workforce. The ECF features technical presentations given by the ECEs to their peers, senior engineers, and Technical Fellows.   <\/p>\n\n\n\n<p>The 12th Annual SLAMMS ECF was held at MSFC and virtually. Sixty-six ECEs, Technical Fellows, TDT mentors, and discipline managers from the SLAMMS LWG were in attendance. ECEs from 8 centers made 16 technical presentations and 18 posters, which were ranked by mentors for the top awards. Multiple splinter sessions provided ECEs with opportunities to ask career-related advice from Technical Fellows, project and systems management, and individuals experienced in design, analysis, and testing. In addition, there was a detailed discussion for each of the technical disciplines represented at the forum, and multiple site tours were provided. <\/p>\n\n\n\n<p><\/p>\n\n\n<div id=\"\" class=\"hds-media hds-module wp-block-image\"><div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\"><div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-cover \"><a href=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art2.png\"><img fetchpriority=\"high\" decoding=\"async\" width=\"2048\" height=\"1536\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art2.png?w=2048\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"\" style=\"transform: scale(1); transform-origin: 52% 60%; object-position: 52% 60%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art2.png 4000w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art2.png?resize=300,225 300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art2.png?resize=768,576 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art2.png?resize=1024,768 1024w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art2.png?resize=1536,1152 1536w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art2.png?resize=2048,1536 2048w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art2.png?resize=400,300 400w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art2.png?resize=600,450 600w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art2.png?resize=900,675 900w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art2.png?resize=1200,900 1200w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art2.png?resize=2000,1500 2000w\" sizes=\"(max-width: 2048px) 100vw, 2048px\" loading=\"eager\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">Attendees of the 12<sup>th<\/sup> annual SLAMMS EFC at MSFC 2023.\u00a0<\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<p><strong>The Future of the SLAMMS ECC<\/strong> <\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>The SLAMMS ECC will continue to evolve as discussions with the ECE leadership team and Technical Fellows continue towards mapping its future.

Pyroshock is the transient response of a structure to loading induced by activation of attached or incorporated pyrotechnic devices. Typical pyrotechnic devices include frangible bolts, separation nuts, and pin pullers that are used to assemble, separate, and reconfigure spaceflight hardware during a mission. Shocks can easily propagate through structure and damage sensitive components. Thus, successful pyroshock testing is considered essential to mission success. At the request of the Gateway Program Chief Engineer, the NASA Chief Engineer initiated an inquiry to reevaluate shock testing approaches for both unit and major assembly flight hardware and requested recommendations for potential revisions to NASA-STD-7003B, Pyroshock Test Criteria, that would clarify the guidance and applicability to new programs. The work delves into topics of shock acceptance and qualification testing for unit and major assemblies, shock test tolerances, shaker shock testing, and the distinction between mechanical shock and pyroshock testing. It also provides recommendations for their inclusion in the next Agency-wide revision of NASA-STD-7003B.  <\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>Current NASA-STD-7003B Requirements<\/strong> <\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>Unit and major assembly flight hardware acceptance and qualification testing are discussed in NASA-STD-7003B. It requires that all units go through shock qualification testing, with few exceptions. The purpose of a qualification test is to verify the design integrity of the flight hardware. The standard calls for pyroshock qualification testing of nonflight hardware for externally induced environments to be performed with a 3 dB margin added to the maximum predicted environment (MPE), with two shocks per each orthogonal axis. Qualification tests are performed on hardware that will not be flown but is manufactured using the same drawings, materials, tooling, processes, inspection methods, and personnel competency as used for the flight hardware. The flight hardware is not recommended to go through shock test, therefore, it lacks workmanship screening testing. The required random vibration (RV) test is considered to be a partial workmanship screening, covering only up to 2000 Hz. A full workmanship screening test for unique and sensitive hardware that may have modes above 2000 Hz needs to be evaluated on a case-by-case basis by an expert in pyroshock dynamics and approved within a program\u2019s risk management system and\/or governing board. <\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>The major assembly acceptance and qualification testing are not recommended, considering that the MPE and design margin cannot be demonstrated at the system-level tests. The major assembly unmargined testing, however, may achieve three objectives. First, the functional demonstration of shock separation devices\u2014probably the most important part of the major assembly level testing\u2014demonstrates the source electrical and mechanical hardware functions as expected, and the interface separates without any issues. Second, the major assembly testing provides the validation of the unit shock environments.  <\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>Third, the major assembly testing provides transfer functions (TF) that may help to estimate the attenuation\u2014and in some cases structural amplifications\u2014throughout the system with all assemblies in flight configuration. NASA-STD-7003B contains discussions for the first two major assembly test objectives. However, there are no discussions on the third test objective related to the TFs. The TFs provide qualitative assessment of shock propagation paths and attenuations at joints and interfaces. The TFs may be used qualitatively as attenuation is highly dependent on the materials and joint construction and may be different if there are changes in the system configuration.  <\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>Suggestions for Improving NASA-STD-7003B<\/strong> <\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>The shock tolerance specified in NASA-STD-7003B is \u00b16 dB from 100 Hz to 3 kHz and +9\/-6 dB above 3 kHz. The constant \u00b16 dB tolerance bandwidths across all frequencies are possible, as many existing shock simulation systems are able to simulate shock signatures that fall within these tolerances without difficulty. These tolerances are based on practical test implementation and shock simulation equipment consideration. The tolerance tightening should be considered at the flight hardware resonant frequencies to avoid over\/under testing. However, if detonator or explosive shock simulation systems are used to qualify flight hardware, the shock tolerances above 3 kHz may be kept at +9\/-6 dB.  <\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>Measurements from many different pyro\/non-pyro separation systems have been shown to have broader shock signatures and do not support the mechanical shock as being applicable to low- and mid-frequency shocks only. The standard discusses this topic and has an example of far field SRS indicating shock energy above 2 kHz. The future revision should clarify the applicability of the mechanical shocks to be broader and not to be limited to 2 kHz and below (see figure below). <\/p>\n\n\n<div id=\"\" class=\"hds-media hds-module wp-block-image\"><div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\"><div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-cover \"><a href=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art4.png\"><img loading=\"lazy\" decoding=\"async\" width=\"2010\" height=\"1052\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art4.png?w=2010\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art4.png 2010w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art4.png?resize=300,157 300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art4.png?resize=768,402 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art4.png?resize=1024,536 1024w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art4.png?resize=1536,804 1536w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art4.png?resize=400,209 400w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art4.png?resize=600,314 600w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art4.png?resize=900,471 900w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art4.png?resize=1200,628 1200w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art4.png?resize=2000,1047 2000w\" sizes=\"(max-width: 2010px) 100vw, 2010px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">\u00a0<br>An example shock response spectrum (SRS) obtained from a mechanical shock separation system, indicating a broad signature is produced by pyro devices.\u00a0\u00a0\u00a0<\/div><\/figcaption><\/div><\/div><\/div>\n\n<div id=\"\" class=\"hds-media hds-module wp-block-image\"><div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\"><div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-cover \"><a href=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art5.png\"><img loading=\"lazy\" decoding=\"async\" width=\"1920\" height=\"1080\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art5.png?w=1920\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"\" style=\"transform: scale(1.2); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art5.png 1920w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art5.png?resize=300,169 300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art5.png?resize=768,432 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art5.png?resize=1024,576 1024w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art5.png?resize=1536,864 1536w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art5.png?resize=400,225 400w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art5.png?resize=600,338 600w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art5.png?resize=900,506 900w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/03\/techup2023-pg52-54-art5.png?resize=1200,675 1200w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">The Gateway Program has benefitted from the updated guidance recommended for NASA-STD-7003B.\u00a0<\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<p>Even though shaker shock testing has been used in the past and is still used by some NASA organizations and contractors, there are multiple technical issues with this type of testing. The shaker-generated shock signatures in the low- and mid-frequency range (typically up to ~2 kHz) provide severe shock environments that may lead to structural failures. Most shakers are also not able to generate SRS above ~2 kHz, therefore, shaker shock test is deficient in meeting the shock requirement up to 10 kHz frequency. NASA-STD-7003B does not recommend the shaker method of shock testing due to the above limitations. This should be emphasized more in the standard. The shaker shock simulation test may be used if it is able to generate time histories that resemble signatures generated by space separation devices, and SRS levels meet the entire frequency range requirements. <\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>For the next NASA-STD-7003B revision, recommendations are being made to include acceptance RV testing for partial workmanship screening testing, add the TFs to be used as qualitative information in assessing the attenuation in the structural shock paths, change the shock tolerance to \u00b16 dB across all frequencies, and consider mechanical shocks to be broader and not limited to low- and mid-frequency SRSs. <\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>In summary, the updated guidance provides clarification to the question\/uncertainty of the applicability of historical guidance to current programs, while ensuring proper applicability to future programs.
