Draft A Two-Page Test Plan For Measuring The Mi

Draft A Two Page Outline Of A Test Plan For Measuring The Minimum Safe

Draft a two page outline of a test plan for measuring the minimum safe arming distance Critical Technical Parameter (CTP) for the SRAW. This should be a DT&E test plan for evaluating the capability of the SRAW to arm itself a minimum safe distance from the Marine that fires it. Follow the guidance on the next page. The SRAW CDD and TEMP can assist you in identifying the proper criteria for this effort and provide other useful information. You can access these documents by selecting the ‘Resources’ button in the upper right area of this page and then selecting ‘SRAW References’ in the pull-down menu.

Your SRAW test plan outline must cover the following seven areas: Test Objective; Test Scenarios/Set-up; Success Criteria; Test Article Configuration; Test Article/Target Requirements; Confidence levels; Test Limitations. The next screen will give you details about specific questions that need to be answered in each area to help focus your response. Your SRAW Test Plan must have the following seven subject area headings. Within them, make sure you address the following : Test Objective: What is the purpose for conducting this test? Test Scenarios/Set-up: Describe specifically how you will set up this test ( in the lab and/ or field ) in order to measure proper functioning of the SRAW CTP.

Do not simply paraphrase the TEMP or describe the overall DT approach. Success Criteria: What defines a successful test? A failed test? Hint: How will you know if an individual test is a success? How will you know if the series of tests is successful?

Define all three conditions: event success, event failure, and successful test series. Test Article Configuration: Describe the test article? Do you need full-up systems, or components? Do they need to be inert or “live”? What instrumentation ( if any ) should the test article have?

Test Article and Target Requirements: How many test articles does the program manager need to buy for your test plan? How many targets do you need? What kind of targets? Hint: Justify your test article requirements using the confidence levels in the next section. Confidence Levels: What is the statistical basis for your test? What confidence level and reliability do you expect your test to demonstrate? How many failures should you assume? What probability distribution did you use ( binomial, exponential, etc. )? Hint: review lesson 11. You may want to use the trusty nomograph provided in the SRAW References under the Resources tab.

Test limitations: Does your test provide enough information to accurately predict the performance of a production SRAW for the minimum safe arming distance parameter? What additional testing may be required to ensure the production SRAW meets this CTP? Submit your SRAW Test Plan for grading via e-mail to your lead instructor at their e-mail address. A passing grade is required for graduation. Your e-mail subject line should read: “SRAW Test Plan”.

Paper For Above instruction

The development and validation of a safe arming distance for the Small Rocket Assisted Weapon (SRAW) is an essential component of its overall safety and operational integrity. This test plan outlines the systematic approach to evaluate the Minimum Safe Arming Distance (MSAD), a Critical Technical Parameter (CTP) crucial for ensuring safety during deployment by establishing the minimum distance from the firing Marine at which the weapon can reliably arm without risk. Conducted as a Developmental Test and Evaluation (DT&E), this plan emphasizes empirical measurement, statistical validation, and configuration considerations to robustly quantify the MSAD and inform design or operational adjustments for full production.

Test Objective

The primary goal of this test is to determine and validate the minimum safe arming distance of the SRAW, defined as the shortest distance from the firing Marine at which the weapon reliably arms under operational conditions. The test aims to verify that the SRAW's arming mechanism functions appropriately at or beyond this distance, thereby preventing arming injuries or accidents while maintaining operational effectiveness. Achieving a clear, measurable safety threshold will support risk mitigation strategies, certification, and guidance for field deployment.

Test Scenarios and Set-up

The test scenarios will encompass both laboratory and field environments, creating controlled and realistic conditions for the SRAW’s operation. Laboratory setups will involve static mock-ups with simulated firing conditions, while field tests will deploy live or inert prototypes at designated ranges. The setup involves mounting the test articles securely, positioning targets at variable distances, and equipping the weapon and target with instrumentation such as sensors for arming status, acceleration, and timing. The field configurations will replicate typical firing environments, including firing from a platform simulating a Marine’s position, to observe arming behavior over the designated distance range. Multiple test runs will be conducted at incremental distances—starting below the expected MSAD and extending beyond—to establish a comprehensive dataset.

Success Criteria

A successful test event is characterized by the SRAW reliably arming when fired from distances equal to or greater than the MSAD during multiple repetitions, with the arming mechanism functioning within acceptable timeframes and parameters. Specifically, success conditions include:

• Event Success: The SRAW arms without failure at or beyond the target minimum safe distance in individual tests.
• Event Failure: The SRAW fails to arm or Arm malfunction occurs at distances equal to or greater than the MSAD.
• Successful Test Series: The series of tests demonstrates consistent arming performance at or beyond the minimum safe distance with a success rate exceeding the predetermined confidence level (e.g., 95% certainty that the true arming distance falls within safety margins), ensuring statistical confidence in the results.

Test Article Configuration

The test articles will include both fully operational SRAW systems and representative components. Full-up units are preferred to replicate actual operational conditions, but inert or safety-verified systems may be used during initial phases. All test articles must include instrumentation such as sensors to monitor arming status, firing parameters, and environmental conditions. Inert units might be used for preliminary tests, while live units will be used for final validation. The configuration must simulate operational parameters, including power supply, launch mechanics, and environmental factors that influence arming behavior.

Test Article and Target Requirements

The testing will require purchasing a sufficient number of test articles—typically at least 20 units—to ensure statistical significance aligned with the desired confidence levels. Targets should mimic operational threat profiles, including stationary and moving targets at varied ranges. Using a mix of uniform and variable profiles, the target setup will facilitate the measurement of arming distances under different conditions, ensuring the robustness of data. Each test will involve firing a single SRAW at designated distances, with multiple repetitions to account for variability and to support confidence level calculations.

Confidence Levels

The statistical basis of the test hinges upon establishing a high confidence level—commonly 95%—that the true MSAD does not fall below the determined threshold. Based on binomial probability distribution, the sample size and failure rate are calculated to ensure this confidence. For example, assuming an acceptable failure rate of 2% (i.e., failing to arm at or beyond the MSAD in no more than 2 out of 100 tests), the number of tests needed is derived from standard statistical nomographs and calculations, such as those provided in the SRAW references. This approach ensures the reliability of the safety margin identified, reducing the risk of premature arming or failure during actual operation.

Test Limitations

The proposed testing approach, while comprehensive, may not fully account for all operational variables, such as extreme environmental conditions or long-term storage effects. Additional testing, including environmental stress testing and extended lifecycle assessments, may be necessary to validate the performance of production units under diverse conditions. The current plan primarily provides empirical data on static distances, and further work may be required to validate performance during dynamic or adverse operational scenarios. These supplementary tests will ensure that the safety margins are robust across the full spectrum of operational use and environmental conditions.

Conclusion

Establishing the minimum safe arming distance for the SRAW via this carefully designed DT&E test plan will significantly enhance weapon safety, operational effectiveness, and user confidence. Through rigorous setup, statistical validation, and configuration management, the plan aims to produce a reliable safety parameter that can guide design improvements, certification, and field deployment strategies. Continuous review and supplementary testing are recommended to address any limitations and to ensure comprehensive safety assurance for the SRAW system.
