SUMMARY OF THE INVENTION

V2 PPRW is derived from and incorporates a general PPRW documented in patent application Ser. No. 16/128,537 filed on Sep. 12, 2018. V2 PPRW, like the general PPRW, is a propeller driven propulsion engine in a pipe profile with props or propellers rotating in part as rotary wings lengthwise along the pipes to propel directional air for lift and drag forces for combined thrust forces transversely through and across the pipe along the length of the pipe; and when vectored, the thrust forces are turned into variable thrust forces for an aircraft takeoffs, landings, and air flights. Unlike the general PPRW, the V2 PPRW is modified for greater propulsion performances by means of shaping contoured airflow field patterns and increased relative airflow velocities around and between props of interacting planet and sun airfoils, and comprising: a sun rotor main-assembly, orbited by a planet rotor main-assembly, and supported by an end mounting main-assembly.

The sun rotor main-assembly is consisted of a plurality of sun rotor sub-assemblies mounted on a pair of sun rotor end plates. The plurality of sun rotor sub-assemblies are clustered in proximity around and in rotations freely from each other, and the plurality of sun rotor sub-assemblies are all rotating in the same directions, either clockwise or counter-clockwise. Each of the plurality of sun rotor sub-assemblies in turn is consisted of one sun rotating shaft, a plurality of sun airfoils, and one sun drive sprockets. The sun rotating shaft and the plurality of sun airfoils are extended in between the sun rotor end plate, the sun rotating shaft continues to pass through and is mounted by free rotation joints to the sun rotor end plates, and the plurality of sun airfoils are fixed attached along and equally spaced in rotations with the sun rotating shaft. Further out from the pair of sun rotor end plates, the sun rotating shaft extends in between and fixed attached to the sun drive sprocket. Each of the plurality of sun airfoils in cross section has a curved segment in shape similar to a semi circle for a high drag sun airfoil with a semicircle chord lying on a radial line from the sun rotating shaft; the curved segment having a radius defined as 1.0*R with its concave surface rotating facing in the same direction in its rotations, pressured against the surrounding air for maximum air pressure resistance, and the sun airfoil in rotations has the appearance of rotational images of one another. Each of the plurality of sun rotor sub-assemblies has the appearance of pipes in profiles.

The planet rotor main-assembly is consisted of a plurality of orbiting planet rotor sub-assemblies mounted on a pair of planet rotating end carrier plates, with the plurality of orbiting planet rotor sub-assemblies equally spaced circumferentially and orbiting in counter-rotations freely in close proximity around the plurality of sun rotor sub-assemblies. Each of the plurality of orbiting planet rotor sub-assemblies in turn is consisted of a planet rotating shaft, a planet airfoil augmented by a paired flaperon, and a pair of planet drive sprockets. The planet rotating shaft, and the planet airfoil augmented by the paired flaperon extend in between the pair of planet rotating end carrier plates, the planet rotating shaft passes through and is fixed attached except by rotation joints to the planet rotating end carrier plates, the planet airfoil is fixed attached along and in rotations with the planet rotating shaft, and the paired flaperon is fixed attached to planet rotating end carrier plates. Further out from the pair of planet rotating end carrier plates, the planet rotating shaft extends in between and is fixed attached to the pair of drive sprocket. The planet airfoil has an appearance similar to a curved segment of a large portion of a semi-circle for a high lift and drag hybrid planet airfoil with a radius substantially greater than 1.0*R and a chord width substantially wider than the sun airfoil chord width, its concave surface persistently facing one direction, and the high lift and drag hybrid planet airfoil appearing as translational image of one another in orbital rotations. The paired flaperon has an appearance of a small portion of a semi-circle segment, nested in close proximity to and having nearly the same radius as the planet airfoil. The planet airfoil augmented by the paired flaperon are concentric in rotations for sharing the same planet rotating shaft as their curved segments centerline with the augmented paired flaperon retracting and deploying around the planet airfoil. The paired flaperon appear as rotational image of one another in rotations around the paired planet airfoil, and in orbital rotations around the sun airfoils of the sun rotor main-assembly. The planet rotor main-assembly and the plurality of orbiting planet rotor sub-assemblies have appearances as pipes in profiles.

The end mounting main-assembly id consisted of one stationary central shaft, one pair of grounding plates, and one pair of gear box and drive assemblies. The stationary central shaft extends in between, passes through, and is fixed attached to the pair of sun rotor end plates supporting the sun rotating shafts of the plurality of sun rotor sub-assemblies. Beyond the pair of sun rotor end plates, the stationary central shaft extends in between and passes through and is fixed attached except by rotational joints to the pair of planet rotating end carrier plates of the plurality of planet rotor sub-assemblies. Further beyond, the stationary central shaft extends in between and is fixed attached to the pair of grounding plates. The pair of gear box and drive assemblies are fixed mounted on and being an integral part of the stationary central shaft extending with the pair of gear box and drive assemblies in between and straddling across the pair of sun rotor end plate and the pair of grounding plate.

V2 PPRW is further comprised of a power and control system to set in motion through the pair of gear box and drive chain assemblies the sun drive sprockets and the planet drive sprockets of the V2 PPRW. Airflow patterns shaped by interacting sun and planet airfoils augmented by the paired flaperons are controlled by such means as flow gates, diverters, ducts, and funnels as appropriate. These and other systems and means and provisions required for the V2 PPRW are neither novel nor unique, and are not further described.

In operations, the V2 PPRW, a propeller driven propulsion engine, has the provided power transmissions and controls system, being powered, in setting in motion through the pair of gear box and drive chain assemblies the sun rotor main-assembly, orbited by the planet rotor main-assembly, and supported by the end mounting main-assembly. The high lift and drag hybrid planet airfoils augmented by the paired flaperons rotating with the plurality of orbiting planet rotor sub-assemblies are in counter-rotations freely around and interacting with the sun airfoils rotating with the plurality of sun rotor sub-assemblies. All sun airfoils rotating with the plurality of sun rotor sub-assemblies by themselves alone are wind generators in drawing in air flowing from the pipe ends and propelling the air radially and tangentially out of the pipe into a pattern of contoured swirling airflow velocity field surrounding the plurality of sun rotor sub-assemblies, producing rotational drag thrust forces only, but neither translational drag nor lift forces. The persistently facing orbiting high lift and drag hybrid planet airfoils augmented by the paired flaperons are counter-rotating at a given velocity in part as rotary wings transitioning through the pattern of contoured swirling airflow velocity field. The high lift and drag hybrid planet airfoils augmented by paired flaperons resultant relative airflow velocities are greatly increased for greatly amplified lift forces, while the resultant relative airflow velocity is greatly increased and decreased favoring for greatly amplified net drag forces aligned in the direction of the lift forces. The lift and drag forces are combined into thrust forces to propel in directions transversely through and across the pipe profile, when vectored, the thrust forces are turned into variable thrust forces. The V2 PPRW, with the planet airfoils augmented by paired flaperons rotating in part as rotary wings, is applicable for propeller propulsion to all propeller driven aircrafts, and as fixed wing replacements for fixed wing and tilt rotor aircrafts.

V2 PPRW, a propeller driven propulsion engine, produce great propulsion performances by shaping airflow fields of sun airfoils and changing relative velocities of interacting sun and planet airfoils. The propulsion performances are overwhelmingly dominated by the performances of high lift and drag hybrid planet airfoils, rotating in part as rotary wings, and having much larger planet airfoils orbiting at a much greater radius than sun airfoils in generating propelled air for lift and drag forces combined into thrust forces. Sun and planet airfoils, interacting in rotations, propel air for thrust forces transversely through and across the pipe profiles along the length of the V2 PPRW. When vectored, the total propelled thrust forces are turned into variable thrust forces for aircraft takeoffs, landings, and air flights.
