- Description
- This is a modification to the synopsis entitled DEVELOPMENT OF HYDROPHOBIC COATINGS FOR USE ON LAUNCH VEHICLE AND SPACECRAFT PROPELLANT TANKS solicitation number NNK15DHC001L which was posted on August 17, 2015. You are notified that the following questions and answers are provided: Question 1: The title of the solicitation is DEVELOPMENT OF HYDROPHOBIC COATINGS... but in the text of the RFI, the phrase lyophilic and lyophobic coatings is used multiple times. Since lyophilic and lyophobic coatings are obviously very different materials, development of BOTH lyophilic and lyophobic coatings for each of the five named liquids will require roughly twice the effort of a project aimed only at lyophobic coatings for those liquids.Please confirm that such an effort is indeed what NASA wants, and if possible please provide insight into why they feel the need for both lyophilic and lyophobic coatings for these liquids. Answer 1: NASA recognizes the scope of this effort and wants to explore the development of both lyophillic and lyophobic coatings. The coatings developed by the study are intended to be used in propellant tanks where some applications will require a liquid repellant coating and others will require a liquid attractant coating. As a reminder, the intent of the RFI is to solicit information about potential sources to investigate the feasibility of using lyophilic and lyophobic coatings and treatments on the inside of propellant tanks in an effort to improve their functionality. The intent of this notice is to gauge industry capabilities and relevant experience in performing the requirements and to determine the appropriate balance of cost, schedule and technical risk. Question 2: The RFI mentions that Phase III (Option II) involves testing and coating; can it be assumed that this would be for each coating on each substrate material of interest. Please confirm and describe the scale of the coating and testing that NASA desires? Would this be restricted to lab bench-scale tests of liquids on flat surfaces, or larger-scale tests involving liters or hundreds of liters of the liquids on or in curved substrates or tanks? And, does NASA know what type of testing is desired in Phase III? Answer 2: NASA contemplates bench-scale type testing for all phases. Question 3: The RFI describes a three phase program over 22 months, with two of the phases described as options. Will the phases have to run consecutively, or can they overlap?If consecutive, will the phases be of equal length? Will the phases described as options only be funded contingent on success of a prior phase?This could be important because equipment and techniques to handle the liquids required during a phase could require significant time and expense for a performer to obtain, and if all of this activity has to occur within a short funded option phase (for example, seven months if the phases are of equal length and consecutive), a performer might require much more concentrated (and thus expensive) efforts than if the phases are all funded from the start of the project and can run in parallel. Answer 3: The additional phases do not have to be consecutive. They may potentially overlap. Question 4: Does NASA require the contact angle measurements and sliding angle measurements mentioned in the RFI to be done with the cryogens as liquids (i.e. at temperatures of 77K and below), or with water at ambient temperature? Answer 4: It is contemplated that the contact angle will be measured with the fluid/metal combinations mentioned in the RFI. For example, the coating designed for use with liquid nitrogen and aluminum needs to be tested with liquid nitrogen and aluminum (@ 77K). The main objective is to quantify how well the coating works. The due date for responses is not extended. Documents related to this procurement will be available over the Internet. These documents will reside on a World Wide Web (WWW) server, which may be accessed using a WWW browser application.
