Benchmark’s non-toxic chemical propulsion system integrated into Spaceflight’s Sherpa-LTC OTV + Ready For Transporter 3 mission

With outstanding hot fire pump tests Halcyon Front non-toxic chemical propulsion system completed at its Pleasanton, Calif., facility, Space reference systemseagerly awaited system has been integrated into Spaceflight Inc.is the first Sherpa-LTC Orbital Transfer Vehicle (OTV).

Sherpa-LTC functionalityIt is a green, high-thrust, twin-thruster propulsion subsystem seamlessly integrated into the available space of the original free flight.

The propulsion OTV must be launched on the SpaceX Transporter 3 mission to take off on January 13 from Cape Canaveral. History of space flights SXRS-6 mission is expected to deliver 13 payloads in the company’s first multi-destination carpooling mission.

Spaceflight is the first to use Benchmark Halcyon Front a two-propellant green system, which enjoys a 25% increase in fuel efficiency over state-of-the-art green monopropellants, using inexpensive and readily available propellants. Designed space flight Sherpa-LTC offer carpooling customers an option of rapid transport in orbit. Benchmark’s Halcyon Avant green bi-thruster system enables satellites to quickly reach desired orbits.

reference Halcyon Peroxide High-test (HTP) based on the single-fuel system has successfully completed recent critical maneuvers and will continue to conduct government and trade missions across three satellites as part of the Halcyon Heritage Campaign which reached orbit on Carrier 2. The Halcyon Avant system uses many common components from its single-fuel predecessor, with the added benefit of a post-catalytic fuel injection feature that provides an almost 100% performance improvement.

The Benchmark team is already working on the second Sherpa LTC propulsion system slated for second quarter delivery to Spaceflight, as well as smaller-scale Halcyon Avant systems for small-satellite commercial and government missions, representing multiple system configurations. which are expected to be in space before the end of 2022..

In its fifth year, Benchmark Space Systems predicts 4-fold year-on-year revenue growth, expands its product and service offerings, and increases production capacity to meet demand and open up exciting new opportunities in the industry. space. The company develops and delivers breakthrough solutions that will not only support the sustainability of LEO, GEO and beyond, but maximize the value of assets in orbit through extended revenue generation and additional capabilities.

Benchmark’s innovative high-thrust system will play an important role in our first multi-destination rideshare mission,” said Phil Bracken, Spaceflight’s VP of Engineering. “We intentionally designed our Sherpa program to be modular so we could utilize best-of-class propulsion systems to meet our customers’ specific launch needs. Our partners play an important role in helping us get our customers exactly where they need to be so they can achieve their mission objectives.”
The collaborative partnership between Spaceflight and Benchmark played a big part in the effective co-development of our first OTV-specific system, poised to deliver on the evolving needs of the Sherpa-LTC product family,” said Ryan McDevitt, Benchmark Space Systems CEO. “Benchmark’s innovative bipropellant system and Spaceflight’s spacecraft design and operational depth and experience capable of delivering Sherpa payloads on orbit with unmatched speed and precision. We are thrilled with the successful hot fire tests and engine integration aboard the first Sherpa-LTC, as we ready for a historic rideshare that opens the door to more access to space.”

Benchmark’s scalable, launch-independent propulsion suite of products and services support a wide range of spacecraft – from 1U cubic satellites to ESPA-class (1-500 kg) satellites, lunar landers, exhausted launch stages and orbital transfer vehicles (OTVs), offering much more safety and faster carpooling options than electric propulsion (EP) systems, which can take months to complete their journeys in orbit.
