Tribute to a friend

Jesuardo_

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…

Flying the Wright Flyer B

Unique experience flying in the replica of Wright Brothers second airplane. Literally open cockpit flight with unconventional controls, makes you built enormous respect for those pioneers and their incredible machines!

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.

F-4 Phantom airfoils – .dat files

mcdonnell_douglas_f_4_phantom_ii_sm

During a recent analysis, the F-4 airfoils were needed and I was surprised that their coordinate data (.dat files) are not found on the web… so they had to be generated with an airfoil design tool. All three airfoils are basic NACA symmetric airfoils with modified roundness and distance of maximum thickness.  Below they can be found and downloaded for anyone interested:

NACA 0006.4-64 (root)

NACA 0004-64 (wing fold-line)

NACA 0003-64 (tip)

And that’s how they look like:

Back to basics – Pre-TPS course 2015

pre-course class

Refreshment course starting in order to prepare the new class students for the demanding flight test year. A 5-week accelerated aeronautics course with calculus, trigonometry, statistics, series, ODEs, root-locus, aerodynamics, compressible flow, aircraft design, propulsion, materials strength, navigation principles and so on, as well as some flying, aims in preparing the pilots and engineers for the theory of the flight test principles and data analysis that follow. Undoubtedly I also find very valuable going again through the basics as every time the understanding goes deeper and the connection of the number crunching to the physical meanings becomes stronger.
