Experience

Born September 3, 1955 Westover air force base Springfield Mass. Raised in St Croix US Virgin Islands. At age 16 worked at fiberglass boat manufacture. From there I subcontracted to boat manufactures to build tooling and custom components this led to custom yacht manufacturing and consulting and semi-custom Glastech 34. In 1983 together with longtime friend built 58’ sailboat and sailed from St Petersburg FL. To the Panama Canal, then the Galapagos islands, the Marquises, Tahiti, Moiré, Raritan, Bo-ra Bo-ra and Hawaii. Have spent much time in Mexico sailed to Isle Mohair’s and worked in San Lose Potosi and Guadalajara. Learning much from the locals of their rich customs.

My hobbies include Sailing, Diving, Restoring Antique car’s and Carpentry and have some experience in piloting aircraft in a Cessna Citroen this has led me to my invention that I believe can help to decrease cost increase production and improve reliability of aerospace products.  I wish to share this technology at no cost and will provide a DVD and information. Below is a description in brief.

I have lots of experience with high-voltage 480 to 600 V electrical systems Building automated systems with electronica eyes stop start mechanisms and analog and digital systems for integrated computer operation writing letter code for said computer system.

I have lots of experience with building diesel engines and all types of mechanical equipment. Hydraulic equipment is one of the things that I have much experience with including building components with my lathe. Painting and finishing of yachts I have lots of experience. Composites I don't even need to say.

A new vacuum-assisted molding technique from Marc Quenneville completely eliminates the seam found in typical composite structures such as aircraft fuselages, wind generator blades, and submarines. Such seams are often bolted together, providing a less-than-optimal connection. The new technique molds large monolithic products using materials such as thermo sets, ceramic composites and carbon fiber reinforced plastic.  According to Quenneville, the technique could even work well to mold seaplanes, armored troop carriers, and large truck bodies. He contrasts it to older methods you’d to build aircraft fuselages existing methods build sections and bond and bolt these parts together these seams are the weakest link and are not reparable further more they add to the cost of the assembly other aircraft company winds filament over polished mandrills, smooth the outsides with CNC machining, and then bolts and tapes the forward and aft sections together, he says. By molding the fuselage in one large pace this machining is eliminated as is the bolting with aircraft the air-conditioning ducts wiring conduits and even the floor can be molded in one shot greatly improving the strength.

In the patent # 7722348 the mold assembly includes a two-piece vacuum chamber. Inside of the chamber is mounted a mold preselected to make a particular monolithic part. In this cases a propeller with fixed blades fore tidal generators and other fixed blade applications inside the mold itself includes a metal central drum with a bottom, top, and stainless steel struts radiating outward these struts give the composite an attachment through the large holes or openings in the struts through witch strands of woven glass weave through the openings in the central drum and through the openings in the struts the strands can be bundles of fiberglass Kevlar Dupont trade mark, carbon fiber or metal coated fiber depending on the application. In turn, a smaller cylinder with micro perforations is attached concentrically inside of the central drum. This creates a toroidal space between the cylinder and the central drum. The micro perforations allow the atmosphere to escape but not allow any appreciable resin to escape due to its viscosity. The rotation distributes the resin evenly to the outer most reaches of the blade mold. Significantly, the resin inside the toroidal space is formed integrally when the resin impregnates the woven glass each blade is there for integrally with the cylinder this eliminates the blade/hub separation problem.

Also included in patent #8029263 is the description to mold hallow components such as wind generator blades and aircraft fuselages and other large hollow components related to transportation and wind energy in this patent there is a description of one axes of rotation or two axes of rotation to simplify this is the one axes of rotation description.

In operation, a tube at the top of the vacuum chamber uses negative pressure to suck the air out of the chamber. Resin or other moldable material is then pumped into the mold threw the rotating connector into the fiberglass which is held in place by the rubber bladder which in the proof of concept machine is a rubber ball. From the resin reservoir located on top of the vacuum chamber. The resin is released into the fiberglass, which is under a vacuum.

The viscosity of the resin prevents the resin from free flowing through the micro perforated hole in the mold into the vacuum chamber. The motor mounted outside of the vacuum chamber rotates the mold via a series of variable speed pulleys and a shaft.

The rotation of the mold creates a centrifugal force which causes the resin in the hollow part mold to flow into the toroidal space in-between the inside of the mold and the bladder. From there, the resin flows along the entire lengths of the woven glass performs, filling each blade mold with resin. The apparatus thus produces a large, molded product having a monolithic structure. The finished product is removed by releasing the vacuum, separating the two chamber pieces, and then separating each of the mold pieces.

Significantly, the resin inside the toroidal space is formed integrally with the resin that impregnates the woven glass. Each blade is therefore integrally formed with the metal hub that bolts the wind generator blade to hub. This eliminates the blade/hub separation problems of previous technology.

The patent # 7722348 is useful in molding fixed blade propellers useful in fan blades tidal generator turbines river generator turbines counter rotating compressor blades ship propellers and other rotating devices having fixed blades around a central hub.

The patent # 8029263 is useful in molding hollow composite parts such as wind generator blades with the metal hubs integrally formed aircraft fuselages seaplanes antiballistic trope transports bullet trains large trucks high performance cars submarines boats sailboat masts oil drill pipe lined cryogenic fuel tanks spacecraft and other things requiring light weight and garter strength.

The invention patent number is 7722348 & 8029263.
