What's the difference between airfoil and slat?

Airfoil


Definition:

Example Sentences:

  • (1) The technique is an adaptation of the principles used by engineers to build complex structures such as ships' hulls, airfoils, and domes.
  • (2) SpaceShipTwo is designed with Rutan’s revolutionary “feathering mechanism”, a shape-changing airfoil that creates a shuttlecock effect on re-entry, and helps the aircraft – unlike those used by Space X and Blue Origin – to land on a runway.

Slat


Definition:

  • (n.) A thin, narrow strip or bar of wood or metal; as, the slats of a window blind.
  • (v. t.) To slap; to strike; to beat; to throw down violently.
  • (v. t.) To split; to crack.
  • (v. t.) To set on; to incite. See 3d Slate.

Example Sentences:

  • (1) Calves were fed milk replacer twice daily while housed indoors in wooden-slatted floor box crates (metabolism cages).
  • (2) In a second experiment, 32 litters of pigs were farrowed in crates equipped with either solid, vertically slatted, horizontally slatted or diamond mesh creep partitions.
  • (3) For the fattening farm the following elements of confinement management were negatively correlated with pulmonary function: fully slatted floor, an automatic feeding system, natural ventilation, and the use of dust masks.
  • (4) The Grade II-listed scenic railway, devastated by an arson attack in 2008, has been rebuilt, wooden slat by wooden slat, back to its rickety, grinding glory.
  • (5) Feed and water were provided on the lower level only and lambs could move freely between levels by means of a slatted ramp.
  • (6) During lay, hens were housed in pens with partly-littered partly-slatted floors.
  • (7) Effects of N-alkyl-N,N,N-trimethylammonium ions with different alkyl substituents (hexyl, nonyl, dodecyl, and octadecyl) on the lateral packing of lipids in dipalmitoylphosphatidylcholine (DPPC) dispersions in H2O was investigated by Raman spectroscopy in a spectral region of 2800--3100 cm-1 at temperatures between 22--70 degrees C. The lateral order parameter Slat calculated by empirical equation reveals that the addition of the ions decreases the lateral ordering of lipid hydrocarbon chains in the gel phase, while in the liquid crystalline state the lateral ordering is increased.
  • (8) Higher slat concentrations (50 mM KCl or 200 mM NaCl) provided partial protection from lysis.
  • (9) Slatted fattening systems are the easiest to adapt to weekly modules of production which limits disease spread between batches and reduces the requirement for medication.
  • (10) Twenty cattle with induced infestations were randomly allocated to five groups of equal size based on the numbers of engorged female ticks which fell through the slatted floor of individual pens during the 3 days prior to treatments.
  • (11) The production results were significantly poorer (with the exception of carcass classification) and the number of culled animals was significantly larger in both slatted floor systems compared with the D-system.
  • (12) A questionnaire sent to 78 producers revealed that tail tip necrosis was seen only in units with fattening bulls housed on slatted floors.
  • (13) Keeping of piglets on slatted metal floor, without complementary iron supply, caused anaemia within seven days from parturition.
  • (14) At weaning, 162 sows were assigned randomly to six groups and housed in individual cages fitted on a slatted floor.
  • (15) There were marked rises in the glomerular filtration rate and calcium excretion but no significant change in slat and water excretion was observed with verapamil.
  • (16) What else is architecture if not a ray of light on a wall?” Below him, a tilted facade of wooden slats sweeps out in a broad arc, forming a streamlined front to the building, before colliding with another curving wall clad with gold-anodised aluminium.
  • (17) A second form of prothrombin is also described, which is not adsorbed into barium slats, and has less than 1% the activity of the normal protein, contains only four gamma-carboxy glutamic acid residues.
  • (18) It has been demonstrated that after experimental infection of pig slurry from the space under the slatted floor (infection dose of 10(6)PFU per ml), the Aujeszky's disease virus (ADV) survived for 72 hours at the temperature of 15 degrees C and at pH 6.5, but was inactivated after 96 hours.
  • (19) The evaporative cooling system, with its open shades and sand bedding, enhanced reproductive performance and milk production compared with that of cows cooled with a spray and fan system with slatted flooring in this hot climate.
  • (20) We then observed that although the number of organisms decreased by 99.8%, their number on slatted floors still ranged between 0.02 x 10(4) and 3 x 10(4) per cm2.
