Turning vane for air duct

An air turning vane and rail assembly for promoting laminar air flow in an angled duct work section, including a pair of rails in parallel spaced apart relation, each of the rails having an elongated body part and a plurality of tabs spaced apart from each other punched from and bent to extend generally perpendicular to the body part in a height distance H, and a plurality of air turning vanes in parallel and spaced apart relation to each other and situated between and perpendicular to the rails in a ladder-like assembly, each of the turning vanes including a single sheet of metal that is folded in a U-bend to form elongated generally rectangular upper and lower walls, each wall having opposite end edges, the vane defining a lengthwise axis extending between the opposite ends, the upper wall in end view defining an arc of first radius of curvature, and the lower wall in end view defining an arc of second radius of curvature greater than the first radius of curvature, with a crescent shaped space defined between the upper and lower walls, and a plurality of crimp spots spaced apart from each other in the lengthwise direction for stabilizing the upper and lower walls in the vane configuration, each crimp spot extending transversely through the marginal portions of the upper and lower walls, each two adjacent crimp spots being spaced apart from each other in the lengthwise direction a distance L which is less than the distance H, and in each of the crescent shaped spaces in ends of the vanes one of the tabs being inserted and bent to generally conform to and fit snugly.

Airship shaped space craft

The present airship-shaped space craft has a middle fuselage extending in a fore-and-aft direction, and a pair of two outer fuselages extending in the fore-and-aft direction located symmetrically on both sides of the middle fuselage. In the above fuselages, gas of a specific gravity of which is smaller than that of air is filled, and the middle fuselage is connected with the outer fuselages by a horizontal wing. The horizontal wing is provided with propelling devices supported in a gimbal fashion for generating thrust in any optional direction, jet engines with backwards directed nozzles to be controlled within a range from a slantwise upward direction to a slantwise downward direction, and rocket engines with ejection nozzles to be controlled in right-and-left and up-and-down directions. During ascent of the space craft, at first the propelling devices, then the jet engines and at last the rocket engines are actuated so as to make the space craft reach and fly along a satellite orbit. Upon return of the space craft, the rocket engines, the jet engines and the propelling devices are actuated in reverse order, and aerodynamic heating at reentry into the atmospheric space can be reduced by making the space craft descend slowly. Also, control of the flight in the atmospheric space becomes easy, so that the space craft can safely and easily land on a predetermined narrow area of the ground.

Anchor rod drill carriage integrating coal mine digging, supporting and transportation parallel fast operation

The invention relates to the field of coal mine underground roadway digging, in particular to an anchor rod drill carriage integrating coal mine digging, supporting and transportation parallel fast operation. The anchor rod drill carriage solves the problems of complexity and time waste of the existing machine debugging process, low roadway digging efficiency, digging and supporting unbalance and the like. A middle frame is of an arc-shaped structure, belt conveyor pin tooth transmission traction mechanisms connected with a mine traction type self-adaptive belt conveyor are symmetrically arranged at the two sides of the middle frame, and the mine traction type self-adaptive belt conveyor passes through an arc-shaped space below the middle frame and extends to a position under a digging machine discharging part; eight sets of drill arms are matched, respectively include four sets of front anchoring and protecting drill arms, two sets of back anchoring and protecting drill arms and two sets of side upper anchoring and protecting drill arms, and are arranged in three rows at the front side and the back side, in addition, each set of drill arms can slide for a certain displacement stroke, the adjustable supporting ranging distance height can be realized, 6-top 2-upper anchor rod supporting can be completed in one step through parallel operation, the supporting time is shortened, the supporting efficiency is improved, a belt conveying passage can be provided, and the one-supporting and one-conveying operation parallel operation can be realized.
