Cool. Can that adequately rule out flutter? it seems that flutter would be complex interaction with the airflow. Is it just a matter of having a high enough resonance frequency?
Of course, the purpose of this test is to meet the regulatory requirements, which are: For aircraft having a VD of more than 200 km/h a ground vibration test including flutter calculation must be performed prior to airborne flutter testing proofing the aircraft being flutter free up to 1,2 VD. The principle of the method consists in creating elastic FEM model and the mass FEM model and put these models together and compared with the ground vibration test. Implementation of aerodynamic inputs is determined (calculated) the lowest speed at which aeroelastic phenomena can occur. This speed must be greater than 1,2 VD. For Sparker, at least approx. 450 km/h can be achieved. These analyzes are performed for several weight configurations, for variants with fixed and free control system and several flight altitudes.
Letadlo mě uchvátilo je nádherné škoda že ho nikdy nebudu vlastnit je nějaká šance že by mě někdo za úplatu proletěl moc po tom toužím a tento letoun je můj sen.
Will this engine / fuel setup allow inverted flight / light sports aeros. I know all Rotax are forbidden and only UL power have an inverted system, but a fast ultralight turboprop capable of the odd roll or loop, especially in tandem seating would be amazing and a dream machine for many.
Nice shape but right side stick sucs when you want to write something to make notes or just to browse data in your phone especially if you are right handed. Light sport was created to give access to fly average income people - with price over 200'000$ you just killing this category make it only for rich people.
Nice design but to fucking expensive!!! Ultra Light class was created with idea to let low income people enjoy beauty of flight. Greedy of produces make it beyond reach of middle income persons. To sad!!!
How are the TL Stream, Tarragon, and Blackshape different? They all seem to be based on the Millenium Master. I cannot wait until these planes are available under LSA rules in the US ... They're all stunning!
