In a collaborative effort involving multiple organizations, the Georgia Tech Research Institute (GTRI) recently carried out radiometric data gathering on two C-130H aircraft. The purpose of this initiative was to compare the heat signatures of the two aircraft and utilize the collected data to update and validate their signature in GTRI modeling and simulation. The ultimate goal is to enhance the aircraft’s flare pattern effectiveness against adversarial infrared threats.
The C-130H aircraft involved in this study were sourced from the 731st Airlift Squadron based in Colorado Springs and the 180th Airlift Squadron located in St. Joseph. Both aircraft have been modified with the T-56-15A Rolls-Royce 3.5 engines, but the primary difference lies in the propeller design. The 731st Airlift Squadron employs the new 8-bladed MP-2000 propeller, while the 180th Airlift Squadron continues to utilize the legacy 4-bladed propeller.
By conducting radiometric data gathering, GTRI aimed to analyze and compare the heat signatures generated by these different propeller configurations. The data collected during this process will serve as vital information to update and validate the aircraft’s signature within GTRI modeling and simulation systems. These systems play a crucial role in determining the effectiveness of the aircraft’s flare pattern against potential infrared threats posed by adversaries.
The comparison between the two C-130Hs allows researchers to evaluate the impact of the propeller design on heat signatures. This data-driven approach enables GTRI to make accurate assessments regarding the performance of the newer 8-bladed MP-2000 propeller in comparison to the legacy 4-bladed propeller. Such insights are instrumental in identifying potential advantages or drawbacks associated with specific propeller configurations.
The information gathered by GTRI will be utilized to refine and improve the aircraft’s flare pattern effectiveness against adversarial infrared threats. Flares are crucial defense mechanisms deployed from aircraft to divert and confuse incoming heat-seeking missiles. By leveraging radiometric data and the resulting analysis, GTRI aims to enhance the accuracy and efficiency of these flares, ultimately increasing the aircraft’s survivability in combat situations.
The collaboration between GTRI, the 731st Airlift Squadron, and the 180th Airlift Squadron not only facilitates cutting-edge research but also allows for additional training opportunities. During the joint efforts in St. Joseph, the 731st and the 180th conducted a formation rejoin, executed a low-level route, and performed air drops of CDS bundles, thereby fulfilling additional training requirements.
