Abstract
The present disclosure is directed to spray boom for aerial spraying comprising an elongate housing operable to be mounted to an underside of an aircraft, the elongate housing defining a hollow cavity, and a plurality of couplings positioned along at least a portion of a length of the elongate housing, wherein each of the plurality of couplings comprises a cylindrical boss that is unitary with and thermally formed from the elongate housing.
Claims15
A spray boom for aerial spraying comprising:
- an elongate housing operable to be mounted to an underside of an aircraft, the elongate housing comprising a composition with a thickness of at least 0.08 inches, and defining a hollow cavity;
- and
- a plurality of couplings positioned along at least a portion of a length of the elongate housing, wherein each of the plurality of couplings comprises a cylindrical boss, wherein the cylindrical boss:
- extends partially within the hollow cavity;
- is unitary with and thermally formed by causing the composition to heat to a first temperature by the application of a rotational movement of a tool to the elongate housing;
- wherein the temperature first temperature is between 1900° F. and 2100° F.;
- and
- has a threaded interior surface that is formed while the composition is at a second temperature, wherein the second temperature is lower than the first temperature, wherein the second temperature is a temperature less than 200° F.

A spray boom for aerial spraying comprising:
- an elongate housing operable to be mounted to an underside of an aircraft, the elongate housing comprising a composition with a thickness of at least 0.08 inches, and defining a hollow cavity, wherein the elongate housing comprises an exterior surface;
- and
- a plurality of couplings positioned along at least a portion of a length of the elongate housing, wherein each of the plurality of couplings comprises a cylindrical boss, wherein the cylindrical boss:
- extends both partially into the hollow cavity and partially outward from the exterior surface;
- is unitary with and thermally formed by causing the composition to heat up to a first temperature by the application of a rotational movement of a tool to the elongate housing;
- wherein the temperature first temperature is between 1900° F. and 2100° F.;
- and

A spray boom for aerial spraying comprising:
- an elongate housing operable to be mounted to an underside of an aircraft, the elongate housing defining a hollow cavity, wherein the elongate housing comprises an exterior surface, a thickness of at least 0.08 inches, a stainless steel composition, and a cross section having a substantially ovoid shape;
- and
- a plurality of couplings positioned along at least a portion of a length of the elongate housing, wherein the plurality of couplings are positioned at least 5 inches apart, wherein each of the plurality of couplings comprises a cylindrical boss, wherein the cylindrical boss comprises the stainless steel composition, a threaded interior surface, an opening into the hollow cavity of the elongate housing, and a boss length of at least 0.30 inches, wherein the cylindrical boss
- extends both partially into the hollow cavity and partially outward from the exterior surface;
- is unitary with and thermally formed by causing the stainless steel composition to heat up to a first temperature between 1900° F. and 2100° F. by an application of a rotational movement of a carbide tool of a speed of at least 2500 revolutions per minute (RPM) against the clongate housing;
- and,
- has a threaded interior surface that is formed while the stainless steel composition is at a second temperature that is less than 200° F.
