Thrust in Space : The Nuances of Thruster Valve Design

Posted on Jan 9, 2020 in News & Events |

Published on: January 9, 2020 By: Valcor Engineering Thrust in Space The Nuances of Thruster Valve Design Applications for thruster valves are growing daily. More and more companies are designing rockets, satellites, and reusable space vehicles that require thruster valves to position, maintain, or change vehicle orbit in space. In particular, launch systems designed to place small, micro, and nano satellites into orbit are proliferating. This new generation of satellites is designed to provide everything from communications, imaging, GPS, weather forecasting, climate change monitoring, and even monitoring of farmland irrigation and fertilization needs. The demand for space-based images especially drives the need for more imaging satellites. The thruster valve plays a crucial role in the guidance and positioning of space vehicles, rockets and satellites. The thruster valve must reliably respond to commands from the vehicle guidance system to fire when and for as long as needed to move the spacecraft to a different position. When needed, thrusters do not normally fire for long periods of time. Rather, they are fired in short bursts to control the vehicle position. Since there is no friction in space, a short burst of a thruster results in the creation of motion in the appropriate direction. Once in motion, the vehicle will continue to travel until other thrusters are fired, creating a braking action to slow or stop the vehicle from moving. For example, a satellite in geosynchronous orbit may need its orbit tweaked occasionally to keep it in the right place relative to the surface of the earth. On the other hand, surveillance satellites need to drop to a lower orbit to take images, then raise to a higher orbit to keep them out of harm’s way. For a thruster to do its job reliably, the valves that are part of it must be extremely reliable, and accurately respond when needed. “The design of a thruster valve is no small feat,” states Rich Kelly, Senior Project Engineer. “Many application parameters must be carefully considered before the design process begins.” Typical information required includes fluid pressure, maximum flow, pressure drop, and end connections. Voltage and current limits are also important, since all power for the solenoid valves is provided by solar panels connected to storage batteries. The media is also critical. Thrusters use several liquids to create hot gases to propel the vehicle, including hydrazine, hydrogen peroxide, and nitrogen tetroxide. Smaller satellites use cold gas, typically nitrogen. When the application calls for hydrogen peroxide, special precautions are taken, as hydrogen peroxide can cause corrosion of the solenoid valve components. For reusable space vehicles, eliminating corrosion is imperative in order to provide a long operating life without the need for servicing the valve. Valcor’s extensive...

Valcor Engineering Goes Greener!

Posted on Dec 6, 2019 in News & Events |

Published on: December 9, 2019 By: Valcor Engineering Valcor Engineering Corporation, a world-class designer and manufacturer of custom precision fluid controls, motion controls, and turnkey systems for space, aircraft, nuclear, and scientific/industrial clients, is going greener! Located in Springfield, New Jersey, Valcor makes efforts every day to protect the environment and limit their carbon footprint. Their most recent endeavor involves the installation of 2,194 solar panels on the building’s recently replaced roof. The new solar array generates electricity during daylight hours and can generate up to 700 kilowatts per day. The electricity is fed to the power grid through an electric meter, which records the amount of electricity fed to the grid. At the same time, Valcor draws electricity from the grid through a separate electric meter in the usual manner. Valcor pays for any electricity consumed in excess of the amount fed into the grid. “The solar modules are installed with a 5° tilt to shed rainwater and snow,” stated Dave Bartok, Senior Manager of Valcor Plant & Facilities. “The use of solar power helps Valcor save the need for generated electricity, resulting in less pollution of our air. This is just the most recent effort by Valcor to be a good partner with the planet.” Valcor has been at the forefront of protecting the environment for decades, not only recycling paper, plastics and glass, but also metals recovered throughout the plant, such as brass, copper, stainless steel, and aluminum. Further, all lubricants, coatings, and other liquids used in the machining and manufacturing processes are recovered and recycled. Also, furniture and fixtures no longer needed are donated to local charities, where they are repurposed and given new life. Valcor’s efforts to protect our planet don’t end at the Springfield facility. Valcor’s Scientific & Industrial group works closely with many clients who provide clean energy solutions to their customers. Several clients make conversion kits, using Valcor solenoid valves, to convert over the road and fleet vehicles from diesel to cleaner burning compressed natural gas. Another “green” application involves the purification of natural gas at remote crude oil well-head sites. When pumping crude oil from the ground, natural gas is also recovered, and sent through a purifier that uses Valcor’s solenoid valves. Once purified, the natural gas is stored in tanks, and used to power generators that provide electricity to the wellhead site. Previously, the well operator would have diesel fuel trucked into the site, stored in tanks, and used to power the generators. Valcor’s Nuclear Energy and Power group provides solenoid valves and systems to nuclear power plants around the world. Valcor is one of only two companies in the U.S. that are approved by the Nuclear Regulatory Commission...

White Paper: Avionics Cooling Using Motor-Operated Proportional Control Valves

Posted on Oct 29, 2019 in Events, Home Pieces, News & Events, White Papers |

Published on: October 31, 2019 By: Valcor Aerospace Avionics Cooling Using Motor-Operated Proportional Control Valves The role of avionics in modern air and spacecraft are becoming more complex as they control more of the functions in these vehicles. Ultra-high-speed flight computer microprocessors and related support chips perform most efficiently in a very narrow band of operating temperature. Solid State Relays (SSRs) controlling other parts of the vehicle system generate substantial heat when energized. As flight vehicle designers work to reduce the weight of the vehicle, they are moving towards Fly-By-Wire (FBW) systems to control most or all aspects of the vehicle flight controls. FBW systems require a lot of power to actuate the sub-systems in a modern aircraft. Power demand is at its highest during takeoff and landing, when rudder, stabilizer and flaps are in constant motion. In spacecraft, roll, pitch, and propulsion thrusters are controlled electronically. Maintaining the ideal avionics operating temperature requires a precision liquid cooling system capable of fast response to changes in the thermal load imposed by the avionics. Simple air-cooled systems are a thing of the past. Air cooling cannot provide the necessary temperature precision in response to load changes. Precision cooling of such sensitive avionics and related systems requires a complex system of temperature monitoring and closed-loop feedback control of the cooling media. Many different approaches are considered when designing the temperature process control scheme of an avionics cooling system. Most industrial commercial off-the-shelf (OTS) temperature controllers monitor the coolant and turn an electric heater on and off to achieve the desired temperature. While relatively inexpensive, they are unable to react to rapid changes in coolant temperature. The electric heater must warm up, and cool down, in response to changes in the coolant temperature. This could take many seconds. For air and spacecraft, these OTS solutions are certainly not sufficiently reliable or fit for use in avionics cooling systems. For flight applications where coolant temperature must be precise to protect sensitive electronics, the use of a proportional flow controller will provide faster response to changes in process temperature. Proportional flow control is achievable in many ways. Traditionally, a pulse-width modulated (PWM) solenoid valve is used to control the flow of the coolant. Pulsing the valve controls the desired temperature of the process media by increasing or decreasing the coolant flow. Also known as the bang-bang approach, the solenoid valve is pulsed by the temperature controller to alter the flow of coolant to precisely maintain the desired temperature for the electronics. Typically fast-acting, the solenoid valve provides good temperature control when new, but solenoid valves can have a finite life in high-frequency cycling, continuous duty service. As the valve wears, its performance degrades. Longer...
