WORLD OF TEST


ELECTRIC SUPERCAR UNDERGOES AERODYNAMIC TESTING


During the past two years, different generations of the Rima C_Two prototype electric sports car have been put through a series of wind tunnel tests. The objective of the test


programme is to ensure that the aerodynamics perform at the optimum level in terms of performance, range and efficiency when it comes to handling the impact of wind under different driving conditions. The engineering team at the


Croatian company ran thousands of CFD simulations for the C_Two, with each simulation model consisting of over 120 million elements with up to 180 million for the detailed heat transfer models. With real- time testing, it is critical to validate expected results. For this reason, the real-time tests were conducted in a controlled wind tunnel testing environment and on the track.


During the tests, Rimac engineers assessed the car against three fundamental aspects: car efficiency, cooling performance and active aerodynamic systems. All of these are particularly important for an electric car, moreso than for a traditional internal combustion-engined version. For example, on long-distance


trips, the demands for cooling will naturally be lower than when the C_Two is being driven on the track. At the same time, ensuring optimum range from its batteries and the car’s overall ability to fully harness its immense power and torque is also key. The car’s aerodynamics play a


key role in this regard. The C_Two has been carefully designed and engineered with this element firmly in mind. The C_Two has four specific active aerodynamic parts. Everything from the active front splitter and intelligent underbody air


flaps to the adaptable air brake wing prove the C_Two is shaped for performance. The tests have all already


gone extremely well in terms of correlation with the CFD simulations. From the initial C_Two concept to the validation


TEST SYSTEM FOR 5G NR VOICE OVER SERVICE ALLOWS EARLY


Head acoustics and Rohde & Schwarz have successfully verified voice services over 5G NR (VoNR). The test system uses the latest generation of the R&S CMX500 wideband radio communication tester, combined with the labCORE hardware platform from Head acoustics and their ACQUA measurement and analysis software. This setup allows simulation


of a voice connection in both 5G (VoNR) and 4G (VoLTE) networks. This enables manufacturers of 5G capable telecommunications devices to test the voice quality


of their devices at an early stage before market introduction. Based on the R&S wideband


radio communication tester for 2G/3G/LTE and WLAN, the new test scope allows 5G NR devices to be tested in both standalone (SA) and non-standalone (NSA) TDD and FDD mode. The R&S CMX500 supports the sub-6GHz (FR1) and mmWave (FR2) frequency bands and provides all required technologies for VoLTE and VoNR calls in both SA and NSA mode.
