Here’s What Grounded The Navy T-45 Goshawk Jet

On October 14, 2022, the Navy decided to ground all of its T-45C Goshawk jet trainers due to concerns for the safety of its aviators. According to Rear Adm. Richard Brophy, Chief of Naval Air Training, this decision was made as a precautionary measure after an engine blade fault was discovered in one of the training aircraft. The grounding affected all 193 aircraft in service.

The Navy, along with its industry partner Rolls Royce, conducted a two-week safety pause to investigate the issue. This came after a training aircraft experienced a low-pressure compressor blade failure prior to takeoff.

In late October 2022, the Navy resumed flight operations for some of its T-45C Goshawk jets. However, the Naval Air Systems Command stated that their investigation revealed a subset of T-45C engine blades did not meet the manufacturer’s specifications, resulting in those specific aircraft remaining grounded. The exact number of affected jets was not disclosed by the Navy, but the partial resumption of flight operations indicates that efforts are underway to address the issue, although a resolution for the entire fleet has not been achieved yet.

Audi Q4 e-tron: 5 updates that make it even better

In sports, trainers often mention the concept of marginal gains: focusing on refining each individual element of the overall package to create a significantly improved overall product. This applies to the updated Audi Q4 e-tron.

The revised Audi Q4 e-tron boasts a more efficient powertrain with increased power, extended range, and faster charging capabilities. Additionally, it features an improved chassis for a more engaging driving experience, and enhanced in-car technology. Here are the key improvements that set the updated Audi Q4 e-tron apart.

#1 Improved Range Efficiency

The Audi Q4 e-tron SUV and Sportback have consistently offered significant all-electric range within their compact urban-friendly design. The updated Audi Q4 e-tron line-up now takes this even further.

This enhancement is made possible by a more efficient electric motor on the rear axle – a permanently excited synchronous machine (PSM) that utilizes optimized thermal management and energy-saving cooling to improve efficiency.

Consequently, the updated Audi Q4 e-tron range now offers increased mileage, with the Audi Q4 Sportback 45 e-tron providing up to 349 miles (WLTP).

#2 Enhanced Performance

In addition to extending the all-electric range, the more efficient rear-axle electric motor in the updated Audi Q4 e-tron also delivers improved performance.

For rear-wheel drive Audi Q4 45 e-tron models, the power output has been raised to 286PS, while the range-topping twin-motor Audi Q4 55 e-tron quattro models boast up to 340PS, achieving 0-62mph in just 5.4 seconds.

This added performance is accompanied by a unique acoustic signature within the e-tron range. As an optional feature, the new all-electric engine sound adapts based on the accelerator position and vehicle speed, delivering a distinct and progressive tone.
