Astro Mechanicatook the first step of a groundbreaking innovation in the aviation world. Founded by Ian Brooke in 2021 and operating with just eight employees, this innovative startup adaptive turboelectric motor He is working on a technology called. This engine hem subsonik (subsonic) as well as supersonic It promises to offer high efficiency for (supersonic) flights.

What is a Turboelectric Adaptive Engine?

This engine developed by Astro Mechanica is a traditional combines features of turbojet and turbofan engines. This system, inspired by electric vehicle engine technology, is a turbogenerator It produces electricity and this electricity powers high-performance electric motors that operate the compressor and turbofan independently. Thanks to this innovative structure, the engine increases fuel efficiency and optimizes speed performance by controlling the amount of compressed air.

This may sound complicated, but it’s actually quite an ingenious method; It separates the fan and compressor components and mechanically drives the compressor independently with high-performance electric motors similar to those used in the electric vehicle market today.

First firing test looks promising

Astro Mechanica announced the engine in the middle of last month. Gen3 version of 30 percent with power successfully completed the first hot firing test. This test stands out as an important milestone for the real-world applicability of the technology. The engine operates in three different modes to adapt to different flight conditions:

  • Mod 1: In this mode the engine does not perform any active combustion. The electric motor drives a component the company calls a “blisk,” which combines compressor and turbofan function. Blisk has a more compact and lightweight design, unlike traditional fan blades
  • Mod 2: This mode activates turbojet combustion. But unlike conventional turbojets, the engine’s compressor is not dependent on exhaust gases. Instead, the compressor is driven at high speed by electric motors to provide the air required for combustion. A genius detail!
  • Mod 3: This mode offers a structure in which the engine runs entirely on fuel and moving parts are disabled. With a physical effect called “Ram Pressure” that we see in ramjets, the aircraft can perform combustion at high speeds using air pressure from the atmosphere.

This order is very important, this engine is our guest because it does this in a single unit.

Conventional turbojet engines use exhaust gases to spin the compressor fan and draw air in, as we see in fighter jets. More exhaust gas means higher speed. Although these engines operate very efficiently at supersonic speeds, they experience serious problems at low speeds. Turbojets have difficulty compressing enough air for efficient combustion and waste a large portion of fuel.

One of the most striking examples of this is the Concorde supersonic passenger plane, used between 1976 and 2003. Concorde was notorious for its fuel inefficiency; He was consuming approximately 2 tons of fuel just to taxi from the gate to the runway. This clearly demonstrates how inefficient turbojet engines are at low speeds.

Turbofan engines, on the other hand, are designed to move aircraft forward efficiently by moving larger air masses at low speeds. However, at high speeds, the aerodynamic drag created by unoptimized large fans also causes efficiency and operational problems.

A cost effective approach

The most important factor in fighter jets or traditional aircraft engines is cost. For example, the CFM LEAP-1B engine in the Boeing 737 MAX costs approximately $14 million per engine. Astro Mechanica claims that its turboelectric adaptive engines with supersonic capability will be cheaper and maintenance will be cheaper due to the fewer moving parts. In fact, the company is designing this engine to run on liquid natural gas (LNG), which is much cheaper than traditional jet fuel and produces 30 percent less CO2 when burned. According to the company, if the iconic Concorde used this engine, it would have 61 percent more range.
