Some Topics of ASKA's Flight Test Results and Its Future Plan 872317

The quiet STOL research airplane (ASKA) was developed as a research aircraft that would provide high levels of STOL performance at low levels of community noise. The ASKA is a C-l tactical transport, modified to incorporate a USB type propulsive-lift system powered by MITI/NAL FJR71O/600S and equipped the BLC and the SCAS. During first 2 years of flight research, the flight tests have been devoted to confirm the initial airworthiness and system function except the BLC system. But all these tests have been limited to the shallow USB flap configuration without the BLC, because of cracks appeared in the engines. The major subjects in this period were as follows; evaluation of newly developed engine, actual proof of structure, confirmation of different avionics systems and the SCAS, and documenting of fundamental flying quality and performance. We have the flight program that the effort will be concentrated on documenting the STOL characteristics in the low speed region.
