Cruising Together: How the Europeans Tipped the Scales for the Ground‐Launched Cruise Missile
ABSTRACT In the 1970s, the United States adopted the ground‐launched cruise missile (GLCM) despite opposition from the military and the lack of an established military requirement. The case is, thus, at odds with common models of military innovation that rely on military utility and organizational interests for their explanatory power.

Altitude Performance of a Turbojet With Alternate Fuels
To enhance energy security and reduce the environmental impact of aviation, alternate fuels derived from various non-petroleum based sources are being developed. Currently alternate fuels are produced to match the properties of existing jet fuels allowing the new fuels to be used in current fleets concurrently with traditional jet fuel.

Task co‐use and product improvement: An organization design perspective
Abstract Research Summary Co‐using tasks—using the same task to produce more than one product—promises economies of scope. However, task co‐use also ties products together, changing a firm's task network by introducing cross‐product interdependencies. In light of these interdependencies, we identify an unrecognized downside of task co‐use for product ...

Explainable Remaining Useful Life Prediction Using Interpretable Divisive Feature Clustering
ABSTRACT Accurate prediction of remaining useful life (RUL) is critical for effective predictive maintenance. While models like long short‐term memory (LSTM) are effective, they often lack interpretability, even when using explainable artificial intelligence (XAI) methods such as shapley additive explanations (SHAP).

Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

Numerical Investigation of Transonic Axial Compressor Rotor With Leading‐Edge Tubercles
Amplitude, wavelength, and span‐wise location of the leading‐edge tubercles on a transonic NASA Rotor 37 compressor are numerically optimized. An increase in efficiency by 0.52% compared to the corresponding baseline rotor is observed. The location of the shockwave moves downstream of the rotor with 1.91% higher pressure.

Oljekrets behövs i en jetmotor i syfte att smörja och kyla dess inre mekaniska komponenter. Oljan som pumpas från reservoaren passerar igenom värmeväxlare. Oljan injiceras sedan på kullagren som kräver kontinuerlig smörjning och kylning innan den når sitt slutförlopp i botten av tråget där den filtreras och dirigeras tillbaka till reservoaren ...
