Abstract

To stay relevantly supported, jet-engine researchers, designers and operators should follow changing uses of small and large jet engines, especially those anticipated to be used by/in the next generation, JET-ENGINE-STEERED (“JES”) fleets of jet drones but fewer, JES-Stealth-Fighter/Strike Aircraft. [1–19, Figure 5 on WIN-WIN VOLL-ROLL-TARGETING & APPENDIX].

In addition, some diminishing returns from isolated, non-integrating, jet-engine component studies, vs. relevant, supersonic, shock waves control in fluidic-JES-side-effects on compressor stall dynamics within Integrated Propulsion Flight Control (“IPFC”), and/or mechanical JES, constitute key relevant methods that currently move to China, India, South Korea and Japan. [4, 5, 20–31].

The central roles of the jet engine as primary or backup flight controller also constitute key relevant issues, especially under post stall conditions involving induced engine-stress while participating in crash prevention or minimal path-time maneuvers to target. [32–45]. And when proper instructors are absent, self-study of the JES-STVS REVOLUTION is an updating must, where STVS stands for wing-engine-airframe-integrated, embedded stealthy-jet-engine-inlets, restructured engines inside Stealth, Tailless, canard-less, Thrust Vectoring IFPC Systems. [4, 5].

Anti-terror and Airliners Super-Flight-Safety are anticipated to overcome US legislation red-tape that obstructs JES-add-on-emergency-kits-use. [1, 2, 13, 16, 17, 19, 32, 33, 36, 39–41, 43–45].

Updating Jet-Engine Components for Next Generation Jet Technologies

Figure 6:

Jet-Engine components in need of specially supported research to meet next-generation requirements: ILLUSTRATED SUMMARY of identification, key terminologies and brief definitions.

PST Inlet: Post-stall engine-air inlets for Jet-Engine Steering(“JES”) designed under JES-IFPC Rules that dictate inlet shapes and material composition that provide (i) engine stall prevention especially under post-stall next-generation vehicle’s maneuvers, especially jet drones discussed above, (ii) Under LDR (see below) hiding the front Fan and Compressor vanes and blades from being detected by rivals’ radars, (iii) resort to removable “stealth-protruding aero-hump” in front of stealthy engine air inlets, if stealth operation is required (iv) Engine Inlets Design Rules also dictate engine air to follow serpentine-type duct treated with proper duct-surface layers and materials that meet next-generation Low-Detectability Rules (“LDR”).

Vectoring 2D C-D Nozzle: Designed under LDR and JES-STVS Rules, and operated by next-generation IFPC that allows safe mechanical or fluidic JES, as briefed above.

IFPC: Integrated Flight Propulsion Control for next-generation Revolutionary Technology JES-STVS.

BLEEDING: Beyond meeting safe, extant-technology, jet engine IFPC needs, the new revolution may require around 6% additional compressed air bleeding extractable from the last compressor stages to allow fluidic JES, which, if used, adversely affects compressor stall dynamics. Accordingly, the fluidic option must be addressed by anticipated, safe, IFPC, or rejected and replaced with most JES efficient, but slightly heavier, mechanical JES. [figure 1].

JES-STVS: The 1986 Revolutionary Technology [1–6] involving Yaw-Pitch-Roll JES of Stealth, Tailless, “Thrust Vectoring” Systems incorporating PST jet-engine inlets that are well-embedded inside Wing-Jet-Engine-Body and safely controlled by IFPC, often without canards, but in anticipated future, without CAFC technologies to field low-cost fleets of “pure” JES-Drones banning LDR and CAFC-based rudders, stabilizers, ailerons.

CAFC: Conventional, Aerodynamic-only, (stall-sensitive, dangerous, partly obsolete in comparison with Complete JES) Flight Control, which is based on rudders, stabilizers, ailerons, etc. and is thus responsible for most crash accidents. [19, 32–45].
