Samara University named after Korolev has begun testing bio-additives in aviation fuel, which will reduce emissions into the atmosphere. The tests will take seven months. The goal of the work, as noted at the university, is to create a fuel formula of the future based on studying the effect of additives on engine characteristics.
So far, experiments are underway on small-sized gas turbine engines (MGTD), including those of its own design, such as the MGTD "Kolibri". These are compact and lightweight engines weighing about two kilograms, on the basis of which it is possible to create mobile power plants and small high-speed aircraft. Experiments with biofuel mixtures on MGTD have not been conducted before.
On the test bench, during engine operation on fuel with the addition of biocomponents, thrust, fuel consumption and environmental friendliness are measured while maintaining the necessary power. During the experiment, the composition of the fuel is changed to find the optimal ratio of components: alcohols, ketones, aldehydes and ethers added to aviation kerosene. During the experiments, scientists plan to bring the proportion of bio-additives in the fuel mixture to 20-25%, and for some components - up to 50%. Adding biocomponents to the fuel should significantly reduce the level of harmful emissions, in particular, soot. The development will allow predicting how the duration, range and cost of the flight will change when refueling the engine with a particular mixture.
Ahead are tests with the participation of aircraft engines for civil aviation, for example, on ПД-8, ПД-14, ПД-35 from ОДК, as well as on a promising gas generator with a thrust of 24 tons.
Earlier, scientists at Samara University developed software that will help Russian airlines switch to sustainable aviation fuel.
