The Sound Man - George Constantinesco and Sonic Power Transmission
Barrie Blake-Coleman
...For one thing, he amassed some 134 granted British patents with possibly another 150 inventions never filed for a patent. Over his life he was responsible for a total of 319 patents filed in France, Germany and the UK, mostly dealing with the control or transmission of motive forces through liquids and solids. For another, he held the gratitude of every British fighter pilot of the first world war as the inventor of the hydraulic interrupter gear that made it possible for allied aircraft to fire their machine guns through rotating propellers. Better, it was said, than the Fokker designed (and somewhat less reliable) interrupter used on German machines.
Moreover, the ever burgeoning automobile market was to give thanks to his sonic oil drilling technique, making it possible to drill deep wells in half the time usually experienced. Indeed, his interest in acoustics and sound, and its application to engineering, made him virtually unique in his inventions and various engineering applications. Unlike many inventors then, it was 'sonics', the application of vibratory or sound transmission to convey energy and power, that was Constantinesco's forte, and accounted for the greater part of his inventive output throughout his life...
In 1915 he disproved the fallacy of liquid compressibility by demonstrating a silent mortar that was capable of launching a 90 Kg projectile well over 1400 metres. It employed super compressed oil at 25,000 psi. Another example compressed a volume of water at 30,000 psi (some 2,000 atmospheres) reducing its original volume by 30%.

Theory of sonics - Invented by George Constantinescu
About Invention
The theory of sonics is a branch of continuum mechanics which describes the transmission of mechanical energy through vibrations. The birth of the theory of sonics can be considered the publication of the book A treatise on transmission of power by vibrations in 1918 by the Romanian scientist Gogu Constantinescu.
History of Sonic Drilling
The roots of sonic drilling technology can be traced back to the efforts of George Constantinesco, a Romanian intellectual who immigrated to England in 1910. Constantinesco formulated the “Theory of Sonics” which was published by the British Admiralty in 1913 and, during that same year, he demonstrated a prototype of a rock drill working on a percussion system, with much success. Unlike pneumatic drills, Constantinesco’s vibratory prototypes were capable of boring through hard granite rock, quietly and smoothly.
Less than 20 years later, another Romanian became interested in sonic vibrations. In 1930, encouraged by the work of Constantinesco, Romanian engineer Dr. Ion Basgan applied sonic vibrations to the drill pipe string of a conventional drilling rig. Amazingly, the result was increased drill depth and speed. The drill was also able to bore a truly vertical hole without distortion, which was not always possible with other methods. Bore holes using this method were drilled at the Moreni oil fields of Romania in 1938 and Basgan received patents on this technique in Romania and the USA. Eventually, this led to interest in developing sonic drilling in the USA by the oil industry during the 1940’s and 1950’s.
Initial research and development of the rotary-vibratory drill began in the United States in 1946. For the first few decades, sonic rig research, conducted by Drilling Research Inc. (DRI), was developed almost exclusively for use in the petroleum industry with the intent of speeding up drill times. Although a lack of funding ended DRI’s research in 1958, American inventor AlbertBodine continued development work on high-powered vibratory machines for various applications including drilling. Most of his efforts (funded by Shell Oil) were directed at large vibratory pile driving machines although his organization eventually developed a smaller vibrator for seismic shot-hole drilling.Funding for the project ended in the late 1960’s and, in the early 1970’s, Bodine sold his drilling and pile driving equipment to Hawker Siddeley, a British aircraft manufacturer with Canadian offices. As a result, renewed efforts to develop the vibratory pile driver and drilling rig came to Canada.
One of the first persons hired for the Hawker Siddeley design team was a young mechanical engineer named Ray Roussy. While the team’s initial efforts focused on the pile driving equipment, later work concentrated on adapting the vibratory shot-hole driver to general shallow earth drilling. From 1974 to 1983, approximately 12 rigs using early sonic technology were constructed and used in different applications. Unfortunately, these first machines experienced frequent breakdowns and lacked appropriate tooling to withstand the associated vibratory forces. The recession of the early 1980’s discouraged Hawker Siddeley from continuing development work in this field. However, the original sonic rig heads and drill rigs built by Hawker Siddeley are still used today.
Ray Roussy left Hawker Siddeley in 1980 to continue development work on the sonic drill head and to adapt it to different applications. Roussy also serviced and upgraded the original Hawker Siddeley drill heads to make them more reliable and he also constructed a number of additional sonic drill heads that were similar. To prove the usefulness of this new technology to the subsurface exploration industry and to carry out long-term reliability testing of his equipment, Roussy built a sonic drill head and drill rig for himself and formed his own contracting company, Sonic Drilling Ltd.
For many years now, Sonic Drilling Ltd. has operated successfully from the Vancouver area, keeping a number of rigs fully contracted on a busy schedule. Mounted with the “Roussy sonic drill head,” these rigs have become well-known favorites for use in environmental investigations and geothermal drilling projects.
As a result of Roussy’s 27 years of research and development efforts, he was awarded a number of US patents for his improvements to sonic drilling technology. Today, Roussy is president of Sonic Drill Corporation, a company which manufactures a product line of sonic drilling rigs utilizing the world’s most advanced and tested sonic drill heads. With his patented technology in use around the world, Roussy can claim credit for not only improving on the efforts of those who went before him but of finally bringing a highly-sophisticated sonic drill to market.
Offering unparalled performance in overburden soil conditions, the sonic drill head can drill three to five times faster than any other on the market – all without the use of drilling mud and with 70-80% less waste. Sonic drills can also provide continuous undisturbed core samples to a depth of 300 feet – a significant advantage over all other drills.
Today, sonic drilling is even being considered and tested for use in interplanetary exploration. Perhaps, 100 years after the publication of Constantinesco’s theory, the first drill on Mars will be a sonic.

THE SONIC ASYNCHRONOUS MOTOR FOR VEHICLE APPLICATIONS
Sebastian Radu, et al.
[ PDF ]
ABSTRACT – Sonic propulsion systems are based on energy transfer using waves propagated in liquids. The major advantages of this process are low dissipation rates and high power density. In order to convert the sonic energy for propulsion goals, an asynchronous motor with liquid rotor was considered. Results of sonic-mechanical conversion processes analysis are presented in the paper. Two different size experimental models were built and analysed.
