- Description
- This amendment to Solicitation Number W31P4Q-07-T-2007 is being issued to post requested answers to additional technical questions not previously posted. Closing date for receipt of quotes is extended until 17 July 2007, noon (CST). TECHNICAL ANSWERS TO QUESTIONS ASKED: 1) Will the dynamometer be provided by the owner? Answer: Yes. 2) Has the dyno been specified? Answer: The technical answers indicate dyno cooling water is not currently required. What type of dyno is proposed (Eddy Current, DC or AC R egenerative)? Answer: The enclosure will be initially, and primarily, used as for propeller testing. At some point it may be used for dyno testing and the cooling water issue will be addressed at that time. 3) Will the energy rejected by the dyno be fed to the electrical grid, or run through an absorber? Should dyno heat rejection be figured into the enclosure? This will have a large influence on refrigeration equipment sizing and cost. Answer: See Answer 2. 4) What test mode will the engine be operated at? Should the heat load be figured for 100 HP at wide open throttle? What time duration will the engine operate at WOT? This will also have a substantial impact on equipment sizing. Answer: Operating limits were provided for material selection purposes. We are not asking the vendor to remove any heat load. The removal of the heat load will be provided for in another effort. The engines will run in the chamber anywhere from a few minutes to 12 hours a day. 5) What time frame is desired to bring the chambe r within the range of the testing temperature? Answer: We are not asking the vendor to provide temperature or humidity conditioning. 6) What tolerance is allowed for the temperature requirements? Answer: See Answer 5. 7) The solicitation states humidity should be 0-100 percent RH. Is this over the entire temperature range of -40 degrees F -140 degrees F? If not, can the requirement be stated in terms of dew point temperature? a) 0 percent RH at -40 degrees F can not be achieved practically. 10 percent RH at -40 degrees F translates to a dew point temperature of roughly -75 degrees F. In any case, desiccant dehumidification will be required to reach this temperature. Is this expected in the project scope? b) 100 percent RH at 140 degrees F is roughly 1,100 gr/lb of moisture. The 0.4 percent ASHRAE Climatic Design data for the worst humidity condition found in the world is only 186 gr/lb. Is this level of humidity actually desired? Answer: See Answer 5. 8) What tolerance is allowed for the humidity levels? A nswer: See Answer 5. 9) The technical answers imply the chamber will be placed indoors. Is this a conditioned space? Refrigeration condensing coils should be placed outdoors to reduce building heat load. Answer: The chamber will be indoors in an uncondit ioned space. See Answer 5. 10) Are there space restrictions for the HVAC equipment? Answer: See Answer 5. 11) How will the testing be monitored? Should our proposal included observation ports with heated glass, or a closed circuit camera? Answer: We will provide cameras. 12) Heated door seals are commonly used with this type of environment to prevent humidity from freezing the door shut. At these conditions, a small ante room is sometimes used to maintain humidity levels if it is necessary for the operato r to enter the chamber between tests while at temperature. Should these items be considered in the proposal? Answer: We do not require an ante room. Heated door seals should be considered if required to properly maintain door function. 13) Often, our clie nts also consider adding altitude simulation with engine test chambers of this complexity. Is this something the Redstone Arsenal would like to investigate? Answer: We don't have an altitude simulation requirement, but would like to discuss that capabilit y with the vendor. **ORIGINAL ANNOUNCEMENT**: Solicitation number W31P4Q-07-T-2007 is being issued as a request for quote. The US Army Aviation and Missile Comm and intends to issue a contract for the following requirement: One Acoustic Environmental Engine Test Cell that will be used for Research and Development testing to perform environmental static ground testing of propulsion systems and shall be suitable for testing loaded by either a propeller or dynamometer.
