Over 5,000 engineers and scientists were on hand last week in our nation’s capital for the world’s largest aerospace research, development, and technology event hosted by the American Institute of Aeronautics and Astronautics (AIAA). These aerospace professionals arrived from 44 countries and all 50 states. The 2023 AIAA SciTech Forum was the largest in the history of the 60-year event and continues to grow every year. Nearly everyone in attendance knew the Kulite name as we have been supporting the aerospace community even longer than the SciTech Forum.

Approximately 1,500 students who are actively involved in aerospace research are included in the attendance numbers. In addition to exhibiting, Kulite was also noted in nearly all the technical sessions as either the studies’ primary measurement device or the foundational reference for the computational pressure modeling. Kulite engineers Scott Goodman and Steve Carter were at the booth to introduce dozens of university students to the miniature transducer product line. With 80+ years of combined experience, Scott and Steve were able to assist them with immediate answers and suggestions so they could begin preparations for their aerodynamic research. Kulite pressure transducers are present at every level of aerospace career and product development by providing the key scientific discovery data behind hundreds of advanced degrees awarded each year.

The theme of the SciTech Forum was “Ignite the Future: Explore the Frontiers of Aerospace.” We had a long conversation with the Artemis 1 flight test analysts from NASA Langley and NASA Marshall. They are currently interpreting the data from the launch last November. They reported that dozens of CTL-190S-25A and LLE-17DC-500-25A transducers purchased in 2014 and distributed on the surface of the rocket provided critical launch data to ensure the safety of future flights. The transducer durability has been outstanding as the Artemis rocket core assembly began right after the Kulite delivery and was subjected to repeated acoustic simulations, shaker table testing, cryogenic conditions, fueling operations, and test fires at NASA Stennis prior to lengthy salt air exposure at Cape Canaveral. The aerodynamic data collected using the Kulite transducers on the unmanned Artemis 1 flight will significantly increase the safety of flight on future manned missions to the moon later this decade and eventually to Mars.

Steve Carter and Bud Coleman attended the Turbomachinery and Pump Symposium from September 13th through 15th in Houston, TX. Attendees included design, operations, and maintenance personnel working with rotating equipment for the production of fluid/electrical power and transfer of material in the oil & gas, petrochemical, power generation, aerospace, chemical, and water industries. Kulite has a relatively small presence in the industrial pump and compressor market, but the potential appears to be much larger with new applications being brought in on a regular basis. The visitors to the Kulite booth indicated the rotating equipment business is in a new period of growth including more challenging measurement requirements for which Kulite offers a wide range of solutions.

Customers were interested in the sensing technology to measure pump pressures on a new robotic paint sprayer, high-temperature hazardous area chemical processes, gas combustor acoustics, and high-speed compressor discharge pressure. All of these applications had been seen as high-risk efforts until the Kulite solution was presented. There were also several companies looking to improve their current process measurements and monitoring capability with the identification of advanced pressure measurement technology. Several companies are now considering Kulite transducers for inclusion in new products they are developing.

JP Hilton, Scott Goodman, and Brendan Wilder attended the 2022 TETS Symposium. TETS brings together around 900 participants from the Turbine Engine industry including OEMs, academics, and government employees. TETS is a relatively small show but has a high concentration of decision-makers and researchers. Kulite engineers met with potential new clients and existing customers including one who stated how happy they are with their BME-88/89 products and miniatures. Overall, our clients relayed to us that Kulite is the first and best name in pressure transducers.

At the Symposium, many papers were presented regarding varieties of “pressure gain combustion” including rotating detonation engines (RDEs). RDEs are a challenging measurement environment for a variety of reasons – they require high speed (>5 kHz) high temperature (>500°C) pressure measurements that would accurately reproduce the time-domain pressure pulses. At the Kulite booth, discussions included device designs for reaching measurement goals, high-temperature products and making RDE measurements. Commonly discussed parts included water-cooled units (WCTV, EWCTV), water-cooled jackets (WCJ), high-temperature units (XTEH-10L, XHTL), and remote measurement systems (DWPP-040, KSIT-040-190). Also, 5th-wire measurements were discussed, and multiple contacts found this approach desirable both for temperature accuracy and because they wanted to reduce their overall instrumentation count by replacing temperature transducers with 5th-wire outputs.

Kulite recently hosted United Launch Alliance, Boeing and NASA for an intensive audit and review of the manufacturing and test documentation for some of our pressure transducers that are installed for use on the Artemis II Space Mission. The three day in-depth review was a great success. Kulite provides FLIGHT CRITICAL transducers specifically used for the pressurization systems for the measurement of liquid oxygen and  liquid hydrogen. The ULA,  Boeing and  NASA team met with many Kulite employees that work on these transducers to thank them for their dedication and hard work toward the success of this world changing mission. 

Artemis II is the first-ever crewed test flight of the Orion Spacecraft. This is scheduled to launch on the SLS rocket in 2023. We are proud to be a partner on this mission to return humans to the moon for the first time since 1972.
