3 years of aeroscience… Hola!

The third birthday of aeroscience blog finds it somewhere in Cuba, celebrating with the company of a Cuba libre and Guantanamera rhythm.
A probably expected conclusion of this trip is that people differ across the world, cultures differ, music, languages and religions differ, scenery differs, but what remains exactly the same are the consequences of communism.


PS1: I spent in Cuba 7 days. During my flight back I found myself thinking on political systems. I strongly believe that the effect of communism on the vector of human evolution is to revert its direction. Theoretically, if communism could be applied long enough homo sapiens will eventually become a fish. Fortunately this will never happen as apes would never adopt this political system. 

PS2: Significant part of my mind is back in my country and the difficult times it goes through.

F-5 Supersonic Flight


A qualitative evaluation and supersonic flight in a NF-5B flight took place in KJAX Florida. A unique feeling and experience flying in the front seat of this maneuverable fighter. Maximum Mach number reached 1.1 at 26,000ft while significant part of the flight was performed in the transonic and high subsonic region. Great lessons learnt in the challenges presented in flight testing this category of airplanes and this speed range. The only problem is that now that I have tried it, I want more…

Tribute to a friend


I met Jesuardo at Forth-Worth TX in 2013. He approached me and asked me “Are you the author of aeroscience blog?”. I replied positively. “That’s great, I follow it!” he said.

From that point and throughout that Symposium we spent significant time together, he was very friendly, kindhearted and enthusiastic guy with great respect for everyone, making nice jokes and keeping always a smile on his face. I felt that we were friends from before. I met also his wife, Jesuardo seemed to really enjoy the time he spent with her. By the end of the symposium we greeted each other and made an appointment for the next year. Unfortunately in the Symposia that followed his colleagues always informed me that he was busy and could not attend, till the NATO Symposium in Ottawa. He was a member of the organizing committee, he had to attend. I couldn’t wait to meet him again!

The first morning of the NATO Symposium I went directly to his colleagues asking where I could find him. Their reply came as a shock: “Jesuardo was killed in the A400M crash, last Saturday”….

… It took me few days to comprehend his loss. My thought continually circled around him, his wife and the two children that he left behind, reminding me in the harshest way that flight test can kill…

Fare well my dear friend. We ‘ll meet again…

Customized portable INS/GPS for use in flight test

Existing INS/GPS equipment had to be replaced due to elements reaching service life and the limitations induced by sensor technology of almost 10 years old (very low bandwidths and accuracy). The current system includes a MEMS-based Inertial Measurement Unit (IMU), is portable being able to be connected to a tablet on the pilot’s kneeboard and provides real-time display of a number of parameters. Sensor compatibility with tools like MATLAB and Labview is highly useful and a CAN bus port can render it easily part of a bigger data acquisition system. First results are very promising.
