During startup of a turboshaft engine, which consequence results from insufficient bleed air?

💡 Explanation

Compressor surge occurs because inadequate bleed air hinders pressure equalization. Insufficient mass flow results in boundary layer separation and flow reversal in the compressor stage. Therefore surge is more likely than heat damage, rather than higher temperature issues given start condition durations.

• Which consequence results when excessive vibration occurs, exceeding a reinforced concrete beam's damping capacity?
• Which outcome occurs when refrigerant maldistribution arises within a multi-circuit evaporator?
• Which risk increases when dissolved gases exceed solubility during investment casting?
• Which structural instability results when yielding rebar compromises concrete confinement?
• Which consequence results when transformer saturation occurs due to a DC current component in a three-phase power distribution system?
• Which outcome occurs when excessively high voltage impulses strike an ungrounded electrical power transformer's windings?
