Load Cell Calibration for Rocket Engine Test Accuracy Load cell calibration for rocket engine thrust accuracy is something anyone making rockets should understand. Rocket engine testing represents one of the most critical phases in aerospace engineering, where precision and reliability are paramount. This article explores the fundamentals of load cell calibration for rocket engine thrust […]
The recently extended mission of NASA astronauts Sunita Williams and Barry "Butch" Wilmore aboard the International Space Station (ISS) highlights the critical importance of thrust validation for space missions. Their prolonged stay, resulting from propulsion issues with the Boeing Starliner spacecraft, underscores the necessity of accurate load cell calibration in ensuring reliable spacecraft propulsion systems. […]
The Science Behind F1: Force and Torque Measurements Force and Torque measurements are key in dissecting the Science Behind F1 car design and racing. Brad Pitt's upcoming F1 movie brings the world of Formula 1 racing to the big screen, where precision, engineering, and high-performance calibration define success. While Pitt plays a fictional driver, the […]
Budget Load Cell Tests: Load Cell Shoulder Loading Errors Morehouse has previously addressed load cell shoulder loading errors and thread engagement in videos and articles. Here, we investigate the results of a simple design change we incorporated into our BLC series. Specifically, what occurs if an adapter is removed and the load is applied directly […]
Deadweight Force Machine Stability: Long-Term Reliability in Force Calibration Morehouse has a new paper on Deadweight Force Machine Stability titled "Deadweight Primary Standards: Best Practices and Their Associated Risks for Stability Determination in Compliance with ISO/IEC 17025" Overview Deadweight force machines are considered the pinnacle of force calibration standards, delivering the lowest possible measurement uncertainties […]
Morehouse Budget Load Cells With accuracies better than 0.02 % of full scale, Morehouse Budget Load Cells are the choice for field measurement capacities 500-112,000 lbf following ASTM E4 and ISO 7500 and for calibration laboratories that want to do more with less budget. Morehouse Budget Load Cells feature the following: ASTM E74 performance: Lower […]
Brinell Hardness Testing Brinell hardness testing is likely the oldest method of hardness testing commonly used today and is used to determine the hardness of castings and forgings with a coarse grain structure. The Brinell test itself is an indentation test where a known indenter, for a Brinell test, is a 10 mm ball applied […]
Rockwell Hardness Testing: Rockwell hardness methods are defined in ISO 6508 & ASTM E18. They are probably the most commonly used method to determine a material’s hardness since it is suitable for almost all metals and, to some extent, plastics. Rockwell test measures the permanent depth of indentation produced by a specified force/load on a […]
Vickers Hardness Testing The Vickers hardness test was developed as an alternative to the Brinell method to measure the hardness of materials. The Vickers hardness test is often easier to use than other hardness tests since the required calculations are independent of the size of the indenter, and the indenter can be used for […]
