Test and Evaluation

You are designing a developmental test to verify that the SRAW safe-arm device (SAD) arms the SRAW in compliance with both the Minimum Arming Distance Critical Technical Parameter (CTP) and the Minimum Engagement Range Key Performance Parameter (KPP) identified in the SRAW TEMP. While the impact of the Minimum Arming Distance CTP on SRAW arming should be self-evident, the Minimum Engagement Range KPP dictates that SRAW arming must occur before the SRAW missile reaches that distance. Furthermore, the test should confirm that the SAD performs at a reliability level consistent with the Reliability Key System Attribute (KSA), also identified in the TEMP. The SRAW TEMP provides additional background information and can be found in the “Tools and Resources” link on the left side of the TST102 course navigation overview screen.

Note that this developmental test is limited in scope, addressing only SRAW arming. Items beyond the scope of this test need not be considered.

The test is to be a system-level developmental test that will consist of a number of open-air SRAW missile launches to occur at the China Lake range complex.

The following assumptions and historical information should inform test design:
• SAD design is stable and based on the design of devices already used in similar weapon systems. Additionally, subcomponent and component lab testing and extensive modeling and simulation efforts have all been accomplished with very positive results.
• Instrumentation and telemetry kits that monitor and transmit activity from the SRAW safe-arm device are available for installation on SRAW test missiles. These kits are compatible with the data collection capabilities at China Lake.
• The Technical Evaluation (DT II) Systems identified in the TEMP are the test assets that should be used for this test. These systems can be configured to include either a live (explosive) warhead or an “inert” (non-explosive) warhead that replicates the weight and balance of the live warhead. The warhead type does not affect SRAW flight performance.
• To simplify planning, assume a binomial distribution and use the nomograph provided when addressing the Confidence Levels / Test Article / Target Requirements section
As part of the test design process, answer the questions in each area below using short (1-2 sentence) responses:
• Test Objective: In terms of confirming that the SAD arms the SRAW in compliance with the CTP and KPP requirements mentioned above, what are acceptable SRAW arming distances (or range of distances) in terms of distance from the shooter? Note here that the SRAW arming distance refers to the distance at which the SAD transitions from SAFE to ARM.

 

Sample Solution

meat dish, milk, precooked rice, coffee, tea and toilet paper. This ration pack was very bulky, and the soldiers needed all of this food to survive through the mountains. During WWII the soldiers fought in all different areas and different types of regions such as the the mountains or fighting in tropical islands of Japan. It was a world war so the soldiers need certain types of food to sustain them through the terrains they need to get through.

In current day the ration packs are a little bit different. Most packs are packaged in tough plastic instead of cardboard boxes. The Navy Seals of today have a single blend of plant based nutrients, fats, probiotics, proteins and carbohydrates. The plants in the blend are wheatgrass, cacao, alfalfa, chlorella and spirulina; for the fats side of things they used sunflower, algae, macadamia, chia seed and coconut. For the probiotics they used chicory root, green banana, acacia fiber, psyllium husk and ten probiotic strands. To supply them with carbohydrates they used, tapioca and sweet potato. As for the proteins in the blend they used peas, collagen, whey and pumpkin. For this one single drink it will supply the seals with 400 calories and 27 grams of protein. On the other hand of things with packaged food they had the Sure-Pak MRE which goes back to packaged food. The Sure-Pak MRE provides the soldiers about 1,000-1,250 calories which I believe is not enough to get them through the heat and rough terrain of the Middle East. It contains a meat dish, a side along the lines of beans, a dessert, crackers, peanut butter spread, peanut butter spread, beverage powder, salt/pepper, moist towelettes, napkins, coffee powder, creamer, sugar and a water based heater. For a bit different type of MRE the “Wise Emergency food kit” is a civilian food kit of freeze dried food and it’s used in emergency survival situations; it comes in a large watertight bucket so your food will not get destroyed in emergency situations. A completely different approach on food supply for the soldiers is the “ER Bar.” The ER Bar is a 24,000 calorie food bar used in emergencies only, it provides a 72 hour food supply for a single bar. You are permitted and warned to eat 2 bars per day and there are 6 bars in a pack. They have a 5 year shelf life so you don’t have to really worry about expiration. This really answers the part of is the food enough to support the soldiers over seas and the answer is yes.

The food rations of WWI are absolutely nothing compared to what they are today. The food of today can supply up to 24,000 calories and a 72 hour food supply to a soldier where the diet of a WWI soldier was around 3,000. I believe that we can get the soldiers the nutrients they need to fight but also bring some flavor into their food; most of the food they eat does not have a great taste whatsoever but provides them with the nutrients they need. Since the cost of a MRE in today’s time is about 8.00 for
