GE Aerospace’s Hypersonic Engine Breakthrough Takes Flight

Last month, the race to develop reusable hypersonic aircraft heated up as GE Aerospace unveiled a groundbreaking advancement in high-speed jet engine design, potentially enabling conventional aircraft to reach speeds exceeding Mach 10. According to GE’s press release, the company achieved a world-first hypersonic dual-mode ramjet (DMRJ) rig test with rotating detonation combustion (RDC) in a supersonic flow stream. This breakthrough leverages rotating detonation combustion, a highly efficient power production method, within a dual-mode ramjet/scramjet engine.

Ramjets and scramjets are air-breathing jet engines that excel at high speeds, typically from around Mach 3 up to Mach 5 and beyond, but are less effective at lower speeds. GE’s achievement represents a significant step towards developing dual-mode ramjet/scramjets with extended range, especially when combined with a turbine-based combined cycle (TBCC) propulsion system.

Raytheon to Develop POWER System for DARPA’s Energy Web Dominance Program

The Defense Advanced Research Projects Agency (DARPA) has enlisted Raytheon for the design and development of a wireless, airborne relay system aimed at delivering energy into challenging environments as part of the Energy Web Dominance program. Under a two-year, $10 million contract, Raytheon will create the Persistent Optical Wireless Energy Relay (POWER) system, employing high-altitude unmanned aircraft equipped with laser-based power receiving and transmitting capabilities.

The POWER system is designed to beam energy to high altitudes and relay it across multiple jumps to reach the intended target area, which could be on the ground or another autonomous aerial platform. This innovative approach creates an “energy web,” enabling military logisticians to route energy rapidly where it is most needed. The system offers the potential to provide indefinite endurance to land, sky, or sea-based robots or redirect energy strategically as required.

DARPA’s insect-sized SHRIMP robots could aid disaster relief


Meet the tiny, versatile robots built to navigate high-risk environments.

DARPA’s efforts to propel military technology forward often manifest in a diverse fashion, spanning everything from drone submarine development to a biostasis program that aims to buy more time to rescue soldiers on the battlefield. The SHRIMP program, short for SHort-Range Independent Microrobotic Platforms, is another potentially life-saving initiative that is being designed to navigate through hazardous natural disaster zones.

Cardboard drone has a one-way ticket


In developing regions where lack of road infrastructure is problematic for those in the business of moving goods, drones are already having an impact. But also problematic is the fact that the people sending drones off to do the courier work kinda need them back again. A new cardboard drone being funded by DARPA won’t concern itself with such limitations, with the ability to deliver vital goods and disappear soon after the job is done.

DARPA is building a drone to provide surveillance anywhere in the world


DARPA is on track to unveil a working prototype of its “Tern” drone system in 2018 that could eventually give the Navy and Marines persistent surveillance and strike targeting “virtually anywhere in the world.”

DARPAs Microdrones Designed To Enter Houses

As drone expert, P.W. Singer said about microdrones, At this point, it doesnt really matter if you are against the technology, because its coming. According to Singer, The miniaturization of drones is where it really gets interesting. You can use these things anywhere, put them anyplace, and the target will never even know theyre being watched.

This has been the promise that the Air Force made quite clear in their video early last year about nanodrone tech that you can see below. According to the USAF, Micro Air Vehicles (MAVs), combined with the ability to harvest energy, will enable insect-sized drone swarms to be dropped from military aircraft to stay aloft for a prolonged amount of time, offering a host of functions, including assassination.
