In the development of software, the application of rapid prototyping is sometim used to verify design adequacy Tests may involve operating and logistic support actions that are directly comparable t tasks performed in a reat operational situation (e.g., measuring a performance paramete accomplishing a remove-replace action, and meeting a servicing requirement). Althougl these testy arenot formal demonstrations in a fully operational sense, information pertine actual system characteristics can be derived and used as an input in overall system evalua tion and assessment. Such testing is usually performed in the producer/supplier's facility by engineering technicians using "jury-rigged" test equipment and engineering notes for test procedures. It is during this initial phase of testing that changes to the design can be incorpo rated at minimum cost. For the river crossing bridge design, various elements of the structure can be selected for early test and evaluation to gain confidence that they will perform intended; for example, road- and railbed materials, walkway lighting, toll facilities, segments of superstructure. 6.2.3 Type 2 Testing Formal tests and demonstrations are accomplished during the latter part of detall when preproduction prototype equipment, software, formal procedures, and the e are ailable (Prototype equipment/software is similar to a production configuration th utilized in the field but has not necessarily been fully qualified at tsoi ualified" system is one that represents a full production configuration (as appi through a Critical Design Review) that has been tested and verified throug cycling, shock and vibration tests), reliability qualification, maintainability dem associated with the initial qualification of the system for operational ful completion of performance tests, environmental qualification tests (e.g., tempe tion, and system compatibility testing Type 2 testing primarily refers to that ven se, and a givenExplanation / Answer
1. This answer is well explained in the notes provided.
2. In acoustic testing the acoustic chamber is used, where a vibration environment is created similar to the rocket being launched for simulating a satellite during the launch process. This is done to verify whether the satellite can function normally after bearing such acoustic vibrations. Also these tests verify whether the designs and analysis of the satellite structure meet the acoustic vibration requirements.
These tests are conducted using a vaporizer to gasify liquid nitrogen (source of noise). The flow speed is adjusted with a control equipment and kinetic energy is transformed into acoustic vibrations using noise producer, these are directed into a chamber with the help of speakers to perform the Acoustic Testing of the satellite.
