On the Performance of Highly Aggressive Inter Compressor Ducts

A major research focus of the Institute of Propulsion Technology at the German Aerospace Center (DLR) is increasing engine compressor efficiency. In this context, the intermediate compressor duct (ICD), which connects the low-pressure compressor (LPC) with the high-pressure compressor (HPC) in a civil jet engine is of eminent significance.

Unveiling the Power of Engineering Metabolism: From Cells to Biotechnology

Metabolism, the intricate web of biochemical reactions that sustain life within cells, serves as the powerhouse driving essential cellular functions. At the heart of metabolism lies the provision of energy and building blocks crucial for the synthesis of macromolecules, vital for cellular structures, growth, and proliferation. This complex network comprises thousands of reactions catalysed by enzymes, involving an array of co-factors and metabolites.

Assessing Evidence-Based Training in a Collaborative Virtual Reality Flight Simulator

Imagine training for a life-or-death situation, only to find that the skills you learnt do not translate when it matters most. This gap in training tragically became a reality in the case of Air France 447, where ineffective responses to an abnormal situation contributed to a fatal crash. While flight simulators have long been a cornerstone of pilot training, their limitations are pushing the industry to explore new technologies. Could virtual reality (VR) revolutionise how pilots are trained?

A simple model for the estimation of turbofan engine performance in all airborne phases of flight

The Aeronautical Journal December 2024 Vol 128 No 1330 Global air transport is a significant contributor to anthropogenic environmental impact. The use of kerosene for propulsion produces carbon dioxide and water vapour, both greenhouse gases, plus a mixture of nitric oxide and nitrogen dioxide that changes the levels of atmospheric, ozone and methane, also greenhouse gases.…

On the Cover of HPL: Optical control of transverse motion of ionization injected electrons in a laser plasma accelerator

In recent years, the plasma wakefield acceleration driven by ultra-short and ultra-intense laser pulses has become increasingly mature, which can produce electron beams with ultra-high beam density and femtosecond beam duration; By using this electron beam, a new table-top radiation light source with collimation, ultrafast and high brightness can be produced.…

10 PW peak power femtosecond laser pulses at ELI-NP

The first 1PW laser was commissioned in the USA in the late 1990s with many systems globally coming on-line throughout the 2000s opening up new and exciting areas of science. In the following years many laboratories strived to increase the power, and hence the focussed intensity, to the 10PW regime, to realise new theoretical thresholds of fundamental science. Several lasers throughout the world, are in the process of construction/commissioning to achieve this goal in China, Romania, Czech Republic, and France with others planned in Japan, USA, Russia and the UK. The first of these systems, ELI-NP in Romania, has recently been the first to demonstrate this landmark achievement.

The Light Beyond the Clouds

Beyond the dark clouds there is light. Is this a topical description for the past, present and future of our industry? In the past, it was our ambition to travel fast and above the weather that inspired the development of the jet engine by its inventors, Sir Frank Whittle and Dr Hans von Ohain in the late 1930s and early 1940s.

On the Cover of HPL: Ultra-broadband near-infrared NOPAs based on the nonlinear crystals BiBO and YCOB

Ultrashort and broadband laser sources are formidable tools for a wide range of scientific areas. In the field of ultrafast science, laser pulses lasting only a few optical cycles are used to generate secondary sources employed in probing matter at atomic scales. Such sources are also widely adopted in applications in ultrafast spectroscopy, pump-probe in chemistry, and optical coherence tomography among many other fields.
