Although he had a profitable business selling patented cone-making machines, his real fascination was with flight. NOTE: if interested in Lanier's theories and applications, an incredibly detailed and scholarly 32-page research project is presently (2007) online as a downloadable PDF file. A 23-page version is also available in HTML format via Google search but lacks all graphics pertaining to the text. Lanier Paraplane PL-8 [N4157A] (Lanier via Ron Dupas coll) 110 Paraplane Commuter PL-8 1958 = 1-2pClwM; 150hp Lycoming O-320; span: 20'7" length: 21'5" load: 500# v: 165/151/30 range: 625 ceiling: 23,000'. Controllable slow-flight at 20-25 mph; take-off and land in 60'. [N4157A]. (The name, Paraplane, fell out of copyright and was adopted for powered parachutes c.2000.) Lanier Paraplane II [N9060H] (Frank Rezich coll) Lanier Paraplane II Topps card #3 120 Paraplane I, Paraplane II 1949 = 1pClwM; 90hp Continental A-90; span: 20'5" length: 22'0" load (prototype): 455# v: 120/30-120/28; ff: ?? (p: Leo Riley). POP: 1 test-bed used by Office of Naval Research in STOL evaluation [N9060H]. **Inverted "Vacucell" gull-wing with an air scoop below and vacuum-slots on topoperated by a hand-crank in the cockpitenabled slow flight at 19mph, take-off in 100', a 30 deg climb angle and 40 deg descent angle, and was spin- and stall-proof. Modified Paraplane II showed up in 1949 with a 22'6" wing and was capable of nearly hovering.** 443 Paraplane 1949 = Little data were found, but this was apparently a larger, possibly high-wing, reconstruction of the previous with 180hp Lycoming O-320; v: 171/x/30. POP: 1 [N9060H] (transferred from 120 Paraplane?). Project abandoned c.1955 after failing to attract a market. Vacuplane 1928-33 - A series of experiments to explore Lanier's ideas on low-speed flight. Relative US patents from 1930-33: #1,750,529, #1,779,005, #1,803,805, #1,813,627, #1,866,214, and #1,913,809. **The idea was to adopt the vacuum principle for inherent stability, especially at stalling conditions. Low speed was achieved by placing an upwardly-open concave cell ("vacuum cell") in the center section of the aircraft, most often blending into the fuselage. Slots were also involved. Hence reduced air pressure evolved in the cell which, of course, had a positive influence on the lift.** Most Vacuplanes involved the University of Miami aeronautics department and its director, Prof F H Given, to some degreedetails are sketchy. Vacuplane documentation is chaotic, and likely no one will ever sort it out, so the following information on the XLs should be regarded as a mixture of facts with some added educated guesses. ( Lennart Johnsson) XL-1 1928 = 1pOlwM; Anzani; span: 8'10"(?). The wings were spaced away from the fuselage to allow the air to flow against the vacuum cell. [3505] c/n 1. XL-2 1930 = 1pCmwM; 85hp LeBlond 5DF. Here the vacuum cell was mounted as a separate box on top of the fuselage. Full-cantilever wing with a span of at least 25', reportedly a modified Durand 13 airfoil. Twin fins and rudders. Pilot in an enclosed cabin under the wing. [X816Y] c/n XL-2. XL-3 c.1931 = 1pChwM; span: 13'10" v: 90/x/25; take-off in about 50'. XL-4 1931 = 1pChwM; LeBlond. XL-3 modified with stabilizing wingtip "winglets"; v: 110/x/25. The wing was mounted as a parasol on top of a central pillar which also housed the pilot. [11512] c/n X-141. LVF (XL-5) 1932 = 1p or 2pOmwM; 36hp Aeronca; span: 14'4" load: 225# v: 96/80/30 range: 250. Take-off run: 90'. A **number of pilots found it stable enough not to slip or dive in a stall. In landing it had a tendency to favor a steep descent with control maintained at minimum forward speed.** [X12865] c/n XL-5. Some data refer to it as XL-5> from its c/n. A mysterious, Roman-numbered XL-III referred to in some documents might be identical with this one. --- **** **RON DUPAS COLLECTION** **No. 569.

Fig. 2. There may be a further flap 29 on the upper aerofoil surface, and a further converging passage 17 further forward on the aerofoil. The movable rear wall may comprise a flexible surface 63, 53 of which the upper part is pulled open by a link 66, 58, the lower part only being attached to ribs 64, 43 which pivot at 66, 56 to open the inlet of the passage. The scoop 62 and the flap 74, Fig. 4, both assist in increasing the airflow through the passage, where it is accelerated and then added to the boundary layer on the upper aerofoil surface. It is stated that an aircraft with wings of a cross-section as shown flew at 19 miles per hour without loss of height. Actuation,-The linkage may be controlled by torque tubes 19, 21 which in turn control either rods, as shown, or cables, and/or possibly hydraulic circuitry or electric servomotors. Actuation of torque tube 21 alone will move spoiler flap 29 only (by links 23 and 28), the compensatory mechanisms 24, 26 imparting no movements to arms 47, 69 until arms 46, 68 are moved by torque tube 19. Movement of torque tube 19 opens both the passages 17, 18, the throat of the front passage 17 being controlled by link 34, bellcrank 36 and link 58, and link 32, crank 33 and link 42 controlling the movement of rib 54 pivoting at 56, links 34, 37 transmitting control to similar linkages for the rear passage 18. As the front passage is opened crank 33 transmits via rod 44 a movement to arm 46 of the compensating mechanism 24. This transmits a portion of this movement to arm 47, the portion depending on the position of arm 31. Movement of arm 47 controls flap 57 by link 48, bellcrank 49 and link 51. The rear flap 74 is similarly controlled via compensating mechanism 26. ![](gb1181991-1-2.jpg) ![](gb1181991-4-8.jpg) ![](gb1181991-3-11.jpg) --- ![](0logo.gif) **Your Support Maintains this Service --** **BUY** **The** **Rex Research Civilization Kit** **...
