For example, operating LOP means we'll give up some horsepower--refer again to the graphs on page 14--and therefore be flying more slowly.
Finally, your airplane/engine combination may not run well LOP, or run at all.
At these higher power settings, we should be far enough ROP or LOP to avoid the so-called "red box," highlighted in Figure 2 at left.
We recommend employing LOP techniques in operating piston aircraft engines when they're appropriate.
In our book, the key isn't whether we're ROP or LOP, but whether we're enough ROP or LOP to avoid operating in the red box.
It's one thing to understand why we might want to lean the mixture control to LOP in piston-powered airplanes.
This should get you out of the red box and LOP. If you're uncertain, enrichen the mixture to well ROP and leave it there.
Many believe one needs a fuel-injected engine to run LOP. Not so.
The general tendency was assessed for the surface regions to be slightly enriched in LOP (Fig.
A very important general question is why the LOP lamellae are formed.
Since The polymers of The blends were completely immiscible, a linear relationship between density and volume fraction of LOP is expected:
where [rho] is the density of the blend, [[rho].sub.PE] is the density of PE (= 941 kg/[m.sup.3]), [[rho].sub.LCP] is the density of LCP (= 1400 kg/[m.sup.3]), [[rho].sub.Nu] is the density of Nucrel (= 940 kg/[m.sup.3]), [v.sub.LCP] and [v.sub.Nu] are The volume fractions of LOP and Nucrel in the blend.
The void contents in The different blends were as follows: Vectra A950 blends: 0.6% (1 vol% LOP), 2.1% (4 vol% LOP), 2.4% (9 vol% LCP), 4.9% (18 vol% LOP), 4.3% (27 vol% LOP) and 8.8% (47 vol% LOP); Vectra RD501 series: 0.7% (1 vol% LOP), 1.9% (4 vol% LOP), 2.8% (9 vol% LOP), 4.3% (18 vol% LOP), 4.8% (27 vol% LOP) and 9.9% (47 vol% LOP).
There is a close analogy between the LOP particles and the crystallites in semicrystalline polymers in that both are almost impenetrable for oxygen.
where [D.sub.O2] is the oxygen diffusivity of the blend sample with LCP, [D.sub.O2] ([v.sub.LCP] = 0) is the oxygen diffusivity in the pure matrix polymer, [beta] is a factor taking into account the constraining effect of the LOP phase on the penetrable PE phase.
