Despite the COVID-19 outbreak and various related restrictions as identified at national level, in September 2020 a full scale ground cabin demonstrator for more affordable small aircraft was built and assembled. This represents a major milestone toward the achievements of the expected goals.

The Clean Sky Core partner SAT-AM “More Affordable Small Aircraft Manufacturing” project is investigating different design and manufacturing technologies that are potentially affordable for Small Aircraft Transport and assessing their suitability for reducing operating and recurring costs. The technologies under investigation include: friction stir welding, additive manufacturing (aka 3D printing), block structures, high speed machining, out of autoclave composites, superhydrophobic coatings, and structural health monitoring. The idea is to assess, down-select and validate at aircraft level the most relevant technologies through two full-scale demonstrators referred to the PZL Mielec M28 short take-off and landing aircraft. One demonstrator is the full-scale ground cabin demonstrator and the other is the engine nacelle flight demonstrator.

As a next step, a consolidated assessment of the benefits and results coming from the integration of the developed methodologies will be performed at A/C level.  Some results are already available and are very promising. They were able to reduce the number of items by more than 35% the number of joints, and reduce some aspects of the assembly processes by substituting joints and mechanical fasteners such as bolts and screws with new technologies in composites and additive manufacturing.

Similarly, activities on the engine nacelle flight demonstrator are progressing to finally prove the flight viability of the concerned technology.

The consortium undertaking the project is composed of eight entities including Sieć Badawcza Łukasiewicz – Instytut Lotnictwa; Polskie Zakłady Lotnicze; EUROTECH; SZEL-TECH Szeliga Grzegorz; P.W. "Metrol" Dariusz Dąbkowski; ULTRATECH; ZAKŁADY LOTNICZE Margański & Mysłowski; and Italian Aerospace Research Entity. The project received €7m in Horizon 2020 funding under the Clean Sky 2 programme and is part of the AIR ITD.
