Investigation of Circulation Control Airfoils by Means of Jets

Tailoring Fluorescent Probes for Organelle-Specific Imaging and Sensing

“…Generally, three prerequisites are required for constructing the FRET process: 1) distance, donor-receptor pairs should be in close proximity to each other (˂ 10 nm) (Figure 2.10 b); 2) spectral overlap, the absorption spectrum of the acceptor and the emission spectrum of the donor should have a certain overlap (Figure 2.10 c); 3) orientation, the donor and acceptor must in the correct orientation. [58] Compared to PET and ICT, the FRET process is widely used in the development of ratiometric fluorescent nanoprobes. [59] There are three main common designs used to manufacture ratiometric fluorescent nanosystems.…”

Jet circulation control airfoil for VTOL rotors

“…For a thin airfoil (12.5% thickness ratio and less), the relation between C Lp and Cj is given by 3 = 3.54CV/ 2 -0.675CV + 0.156CV/ 2 (4) However, for the elliptical airfoil of 18% thickness ratio, the previous expression does not give accurate results, and approximate estimation of C Lp and Cj must be made.…”

“…4 The tunnel is of the continuousflow, closed-circuit type, capable of a maximum velocity of 175 fps. The closed test section is 38 in.…”

“…The data of the NACA 0012 airfoils are taken from NACA TR 460 and the results of the elliptical airfoil are calculated from the present data. 4 The section drag coefficient of the elliptical airfoil is obtained by taking the difference of the measured values of the jet thrust coefficient and the corresponding calculated values (correction for Re = 3.23 X 10 6 was made). Since the measured values of the jet drag (Fig.…”
