About this file
This is a NASA Shared Services Center Recommendation and Determination to Solicit from One Source or Brand Name document. The document recommends a brand name justification to negotiate exclusively with VasyFan SRL for the procurement of specialized electric propulsion equipment. The procurement includes Quantity 2 VF-570 Electric Ducted Fans (EDFs), Quantity 2 air-cooled Electronic Speed Controllers (ESCs) model JLM-430V-400A AC, and Quantity 2 liquid-cooled ESCs model JLM-430V-400A LC. The estimated period of performance or lead-time for delivery is 15 weeks after award; the total estimated cost is redacted in the document.
The justification for single-source procurement is based on unique technical specifications that only VasyFan can meet. The EDFs must have a 570mm internal cylinder diameter, maximum thrust of 1700 N or higher, maximum rotational speed of 6000 RPM or higher, maximum input power of 100 kW, and total engine weight of 31 kg or less. Both air-cooled and liquid-cooled ESCs must have a continuous power rating of 100 kW nominal, maximum voltage of 450 VDC, maximum current of 520 A, and manufacturer approval for compatibility with the EDF. The project team conducted market research and explored alternative vendors including Schubeler, WeMoTec, HobbyWing, and XFly-Model but determined that none market products meeting the same or greater performance specifications. The document notes that using alternative vendors would result in project failure, major redesign requirements, schedule delays of several months, cost implications, and degraded system performance below originally intended capability.

OR BRAND NAME
PICK ONE
Sole Source:
I recommend that NASA, NASA Shared Services Center negotiate with Vendor Name only for Enter Supply or Service to be procured. The total estimated cost of this effort is Enter Dollar amount and the estimated period of performance or lead-time for delivery is Date.
OR
Brand Name Justification:
I recommend that NASA, NASA Shared Services Center negotiate with only with vendors who can provide the subject band name from VasyFan SRL for Quantity 2: VF-570 EDFs, Quantity 2: ESC 100kw, JLM-430V400A AC. (Air cooling), and Quantity 2: ESC 100kw, JLM-430V-400A LC. (Liquid cooling) .
The total estimated cost of this effort is and the estimated period of performance or lead-time for delivery is 15 weeks after award.
This recommendation is for the acquisition of supplies or services determined to be reasonably available from only one source/only one manufacture. Competition is impractical for the following reasons (please answer the questions below):
1. What are the reasons for soliciting only the suggested source/suggested brand name? Please provide the unique characteristics of the items or services along with the supporting rationale and the market research performed to substantiate your reason for the suggested source/brand name.
The project requires (2) Electric Ducted Fans with the following specifications:
Internal cylinder diameter: 570 mm Maximum thrust: 1700 N or higher Maximum rotational speed: 6000 RPM or higher Maximum input power: 100 kW Total engine weight: 31 kg or less
The project requires two (2) air-cooled ESCs meeting the following minimum specifications:
Continuous power rating: 100 kW nominal Maximum voltage: 450 VDC Maximum current: 520 A ESCs must be approved by the EDF manufacturer for compatibility.
The project requires two (2) liquid-cooled ESCs meeting the following minimum specifications:
Continuous power rating: 100 kW nominal Maximum voltage: 450 VDC Maximum current: 520 A ESCs must be approved by the EDF manufacturer for compatibility.
