The detailed design procedure of inlet internal duct has not been very well documented so far in the open literature. The practical technical approach is to design the aerodynamic S-duct, which was first proposed in and later discussed in and .The aerodynamic S-duct simulates the stream tube of the air captured by the submerged inlet, and its relationship …

The influence of centerline and the cross-section variation to aerodynamic performance of the inlet was researched in a wider range. A new method of measuring the total pressure recovery coefficient and total pressure distortion coefficient of the inlet was proposed. Based on the loitering aircraft, a s-shaped inlet was designed to meet the needs of stable flight of loitering …

Submerged inlet definition and working principle . This section presents the numerical simulation result of the submerged inlet. For a more detailed view into the interior of the 3-D flows, the flow situation in symmetry plane T 1 …
A remote submerged chain conveyor system for separating particles from a coal ash/water slurry from one or more remotely located boiler units. A tank forms an ash holding section, a …
A submerged inlet investigation, using flow control in the form of discrete blowing, examined proximity and jet directionality to improve compressor face uniformity. The flow control locations ...
Artist's concept picture of a submerged inlet for a jet aircraft. Three intakes on an engine cowling. Numerous ducts on the Ferrari F40. A NACA duct, also sometimes called a NACA scoop or NACA inlet, is a common form of low-drag air inlet design, originally developed by the U.S. National Advisory Committee for Aeronautics (NACA), the precursor to NASA, in 1945.
A smooth surfaced, submerged air inlet for use generally forwardly of an engine in an aircraft (missile or other air vehicle). The inlet has an opening having wall surfaces adapted to be flush with or inwardly of an aircraft body surface. The wall surfaces of the opening have a leading and outer end in a plane and the surfaces extend inwardly to form an uncovered shallow channel …

The drag and pressure recovery of an NACA submerged-inlet model and an NACA series I nose-inlet model were investigated in the transonic flight range. The tests were conducted over a mass-flow-ratio range of 0.4 to 0.8 and a Mach number range of about 0.8 to 1.10 employing large-scale recoverable free-fall models. The results indicate that the Mach …

Submerged inlet concepts have become an important issue in subsonic drone design studies. Flights of the Boeing MQ-25 Stingray aerial refueling drone in 2019 demonstrated the implementation of such an induction system on a long range heavy UAV. Fig. 1 shows the inlet entrance on top of the drone . Lower radar cross-section and drag, compact ...
The inlet end is submerged and the outlet end flows freely. Again, the flow is supercritical and the barrel flows partly full over its length. Critical depth is located just downstream of the culvert entrance, and the flow is approaching normal depth at the downstream end of the culvert. Figure 2E-2.01C: Inlet Submerged
Submerged inlet ports shall be located so as to avoid creating a disturbance of the settled floc.. Submerged inlet piping shall remain submerged during use and after pumpout.. The five-year cohort graduation rate is calculated using a similar methodology as the four-year cohort rate. Submerged inlet means a water pipe or extension thereto from a public water supply …
Submerged Inlet (Normann, 1985): Outlet Control Outlet velocity (V) is computed based on what we call the velocity depth, Y v. Normann (1985) suggests: If Y t ≤Y c, then Y v =Y c. If Y c
