The en route noise test was designed to characterize propagation of propfan noise from cruise altitudes to the ground. In-flight measurements of propfan source levels and directional patterns were made by a chase plane flying in formation with the propfan test assessment (PTA) airplane.

A propfan, also called an open rotor engine, or unducted fan, is a type of aircraft engine related in concept to both the turboprop and turbofan, but distinct from design is intended to offer the speed and performance of a turbofan, with the fuel economy of a turboprop.

A propfan is typically designed with a large number of short, highly twisted blades, similar to a turbofan's.

All i asked for is when does test prop kick in. Only one guy has said gains are actually visible from 3 to 4 weeks. mg per week of test prop is mg of test E due to ester weight, where mg test E is recommended for a first cycle.

I mgiht add npp on my 2nd cycle, but tbh i just want to stick to test only 6 weekers. Test E, did it for my first cycle and gained a nice clean 15lbs that I was able to keep. Plus like others have said, pinning ED or EOD for first time might be literally a pain in the ass.

Not sure what I would choose, just wanted to know if people run Test and Deca at the same ratio or one of the two higher. Thanks for the post mate, repped. Gusto mo dumugo ilong mo? eto sagutan mo! di ko matandaan lahat ng rinreview ko kaya tignan ko kung effective pag gumawa ng sariling exam.
