Patent number: 7048228Abstract: An aircraft wing includes a leading airfoil element and a trailing airfoil element. At least one slot is defined by the wing during at least one transonic condition of the wing. The slot may either extend spanwise along only a portion of the wingspan, or it may extend spanwise along the entire wingspan. In either case, the slot allows a portion of the air flowing along the lower surface of the leading airfoil element to split and flow over the upper surface of the trailing airfoil element so as to achieve a performance improvement in the transonic condition.Type: GrantFiled: October 3, 2003Date of Patent: May 23, 2006Assignee: The Boeing CompanyInventors: John C. Vassberg, Lie-Mine Gea, James D. McLean, David P. Witkowski, Steven E. Krist, Richard L. Campbell

Patent number: 7048235Abstract: A swept aircraft wing includes a leading airfoil element and a trailing airfoil element. At least one full-span slot is defined by the wing during at least one transonic condition of the wing. The full-span slot allows a portion of the air flowing along the lower surface of the leading airfoil element to split and flow over the upper surface of the trailing airfoil element so as to achieve a performance improvement in the transonic condition.Type: GrantFiled: October 3, 2003Date of Patent: May 23, 2006Assignee: The Boeing CompanyInventors: James D. McLean, David P. Witkowski, Richard L. Campbell

Patent number: 6886778Abstract: Efficient wing tip devices for use with aircraft wings. In one embodiment, an aircraft wing/winglet combination includes a wing having a wing root portion and a wing tip portion spaced apart from the wing root portion. The wing tip portion can have a wash-out twist relative to the wing root portion. The aircraft wing/winglet combination can further include a winglet extending from the wing tip portion of the wing. The winglet can be swept at least generally forward relative to the wing to favorably change the lift distribution on the wing and in turn reduce the induced drag on the wing.Type: GrantFiled: June 30, 2003Date of Patent: May 3, 2005Assignee: The Boeing CompanyInventor: James D. McLean

Patent number: 5099685Abstract: A wind tunnel having a test section and a fan section, interconnected by two passageways to form a recirculating air flow through said sections. There is a diffuser immediately downstream of the test section, and a second diffuser immediately downstream of the fan section. Each diffuser has an intermediate flow section where the side wall extends radially outwardly in a downstream direction at a relatively sharp angle. At the upstream end of the intermediate section there is a peripheral suction slot to draw in boundary layer air, and a by-pass passageway to discharge the air tangentially in a downstream location of the diffuser. This enables a substantial reduction in air velocity in a relatively short axial length.Type: GrantFiled: August 9, 1990Date of Patent: March 31, 1992Assignee: The Boeing CompanyInventors: James D. McLean, Peter P. Sullivan

Patent number: 4440603Abstract: Liquids are monitored for dissolved halogens using amperometric detection based on the use of halogen specific electrodes of a conductive substrate on which is formed an adherent surface film of [Ti.sub.x (Ru, Ir).sub.1-x ]O.sub.2, wherein x=mole fraction .gtoreq.0 to <1, and (Ru, Ir) represents either ruthenium or iridium or mixtures thereof. The described electrodes resist corrosion and failure in extremely harsh environments, e.g., hot concentrated brine solutions.Type: GrantFiled: June 17, 1982Date of Patent: April 3, 1984Assignee: The Dow Chemical CompanyInventors: Richard M. VanEffen, James D. McLean, Dalton L. Decker

Patent number: 4343767Abstract: A flow-through electrochemical cell distinguished by the feature of a working electrode comprising selected carbon black powder(s) dispersed within an inert binder. An outstanding characteristic of the invention is the markedly improved signal/noise ratio of the electrode which enables a significant gain in the sensitivity level at which trace compounds can be detected. As an example of utility, as little as 5 to 30 parts per billion (ppb) of most phenolic compounds in water can be determined by liquid chromatographic separation of species and amperometric electrochemical detection, using the described flow-through cell to monitor the column effluent. No sample preparation is required.Type: GrantFiled: April 9, 1981Date of Patent: August 10, 1982Assignee: The Dow Chemical CompanyInventors: Merton W. Long, James D. McLean, David N. Armentrout, Harold H. Gill

Patent number: 4315609Abstract: A target locating and missile guidance system comprising reconnaissance araft equipped with laser or radar range-measuring apparatus in conjunction with a plurality of selectively predetermined ground stations. Range and altitude of the aircraft relative to a detected surface target are obtained at two or more points on its flight path. The positions of the aircraft with respect to the ground stations are simultaneously determined by pulse-time-of-arrival technique. Using triangulation techniques the location of the target is determined with respect to a pulse grid coordinate system associated with the ground stations. At any time after the determination of the location of the target, properly timed signals from the ground stations or command signals based upon time-of-arrival data with respect to pulses from the missile are used to provide accurate guidance of the missile to the target.Type: GrantFiled: June 16, 1971Date of Patent: February 16, 1982Assignee: The United States of America as represented by the Secretary of the NavyInventors: James D. McLean, Frederick C. Alpers, George R. Lanning, Fred H. Camphausen
